Products in Intrinsic Safety & Process I/O™
MTL is a world leader in products designed for use in hazardous areas where there is a probability of explosive atmospheres.
The products range from industry renowned (IS) barriers and isolators through to sophisticated process control products, all designed for the harsh environments often encountered in the process industry.
As part of our 'Customer Committment' process, we regularly produce educational reference material to assist users in understanding the latest EU regulations and directives.
Functional Safety Management - FSM
Many MTL products are certified as safe for use in hazardous areas; that is places where explosive material may be present. The products are designed and certified to show that they are incapable of igniting the gas or dust and causing fire or explosion.MTL-FSA logo

Another type of safety is called Functional Safety, which applies when products are used in safety and protection systems, in which a failure may mean that a protective system will not operate as it should. MTL products have been used in safety systems for some time, but there are increasing requirements to demonstrate an adequate level of functional safety, especially after the Buncefield, Texas City and Deepwater Horizon accidents. More and more, customers are demanding that products they use in safety systems meet the requirements of the second edition of the IEC 61508 Functional Safety standard, and they require evidence to show that they do. This is to enable the use of our products within instrumentation loops that are designed to achieve a specific Safety Integrity Level (SIL).

When MTL designs a product in the expectation that it will be used in functional safety-related systems, both the design process and the product needs to comply with IEC 61508:2010.

MTL has chosen to obtain Functional Safety Management (FSM) certification for the company. FSM means that MTL has the necessary processes and competence to design products according to IEC 61508:2010. Certification means that a notified body is ensuring that our processes are correct and that we are working to them. Together, FSM Certification gives our customers confidence in the company and the use of our products for functional safety.

Intrinsic Safety Zener Barriers
MTL is a pioneer in the development of the "shunt diode" safety barrier. This is a passive network device that uses Zener diodes, resistors and fuses to safely divert excess electrical energy to ground and thus prevent sparking in or overheating of equipment in hazardous areas. Their key benefits are low cost and the ability to operate with data in analogue DC or high-speed digital forms.

MTL became a world leader with its ranges of shunt diode safety barriers and its support role in the emergence of this new technology.The early MTL700 Series soon established itself as an 'industry standard' with a reputation for quality and reliability.

The ranges have evolved over the years but the latest MTL7700 Series is unique in providing a broad range of benefits that the instrumentation engineer looks for in a modern barrier.

With the new MTL7700, and continuing support for our other ranges, MTL's commitment to zener barriers is confirmed for many years to come.

MTL646 / 647 Series MTL646 / 647 Series
The MTL646/7 text displays are located in the hazardous area where they display alphanumeric data & graphics from a safe area host controller. This is transmitted by a serial data link passing through an MTL5051 isolating interface. This serves the dual purpose of isolating the IS indicator and converting RS232 or RS422 serial data to the MTL signal level and vice versa. Bi-directional communication permits operators to acknowledge messages and to request process action when necessary. If required, an audible or visual alarm can be connected to attract the operators attention.
The MTL647 field mounting unit is housed in a tough impact-resistant case designed to withstand the rigours of hostile weather conditions and harsh industrial environments. Ingress protection rating is IP66. It can be mounted directly onto a flat surface or, with an optional kit, onto vertical or horizontal pipes or posts.

The MTL646 panel mounting unit is designed for DIN standard 72 x 144mm cut-out. The panel/unit seal is rated at IP40 while, with standard ‘snap-on’ mounting clips, the panel/unit seal is rated IP40. This can be uprated to IP65 with the optional IPK68 sealing kit.

Products in HART Interfacing
hart_logoEvery HART® field device is capable of providing significant data about its performance and the process it is controlling. Don't ignore such a valuable asset!
If you have smart field devices installed and you are not making full use of their capabilities, then you need MTL's HART® connection system. MTL has solutions that provide the connections between the HART field instruments, the control systems and the process automation maintenance software. MTL’s HART multiplexer system provides on-line access from a PC to the HART field devices for monitoring device performance. HART devices may be selected for regular status monitoring and alerts to be issued if the status changes.
MTL's HART CONNECTIONS strip the HART digital signal from the 4-20mA signal (which passes to the control system unscathed) and sends it directly to your maintenance PC. Thus giving you access to the benefits offered by the latest powerful configuration and predictive maintenance software.
For process control systems using traditional I/O installations, the NEW MTL4850 or the MTL4840 HART Connection System is the ideal HART solution for new installations or upgrades, either intrinsically safe or general purpose applications.
For process I/O installations, MTL8000 Remote I/O is fully HART compatible, allowing read-and-write configuration and calibration parameters as well as online monitoring of key variables and status.

Products in Industrial Security
Supervisory Control and Data Acquisition (SCADA) and industrial control systems have long been considered immune to the cyber attacks suffered by corporate information systems. The move to open standards such as Ethernet,TCP/IP, and web technologies has allowed hackers and virus writers to take advantage of the control industry’s ignorance. The result is a growing number of unpublicised cyber-based security events that are affecting critical infrastructure and manufacturing industries.
Network Security ~ Overview
Over the past decade, critical control systems have increasingly adopted information technologies such as Windows™ Ethernet™, TCP/IP and web services. Unfortunately this means that PLC, DCS and SCADA systems are now exposed to attack from viruses, hackers and possibly terrorists from around the world.

Supervisory Control and Data Acquisition (SCADA) and industrial control systems have long been considered immune to the cyber attacks suffered by corporate information systems. Despite industries’ best efforts to isolate control systems from the outside world, the bad guys (and bugs) still get in. Traditional firewalls are too complex for most security professionals to configure correctly and are even harder to set up properly on the plant floor. And once a virus or hacker gets past the control system firewall, the typical PLC or DCS is an easy target for attack. Control devices and protocols offer no authentication, integrity or confidentiality mechanisms and can be completely controlled by any individual that can “ping” the device. Nor can they be easily patched or have security features added to them even when security vulnerabilities are discovered.


The fully distributed Tofino™ Industrial Security Solution is much more than a firewall. With its centrally manageable, dynamically Loadable Security Modules (LSM’s) it can provide encryption, intrusion detection and control protocol-aware security solutions tailored to specific plant floor situations. The Tofino™ Central Management Platform (CMP) will configure, monitor and manage the functions of each remote Tofino™ Appliance so that it can be automatically tuned to meet the security needs of the devices it is protecting.
Tofino? Hardware Tofino™ Hardware

The Tofino™ Industrial Security System is a new and unique, solution from MTL and Byres Security that addresses the important issue of protecting Industrial Networks from modern cyber-security attacks.

Simple to Install

The conventional approach is to employ a standard, but highly complex, “IT-style” firewall. Such methods are complicated and require highly-trained staff to install and manage them. Tofino™ was designed with its environment, the level of staffing and the needs of industry in mind. As a result, a field technician can simply attach power to a Tofino™ appliance, connect two network cables and then walk away – it’s that simple to install.

Centralised Control

From there, the company security staff can sit at a central management platform (CMP) and configure and monitor any system with ease, reacting to threats in a coordinated and company-wide manner. Best of all, the system has the flexibility to adapt to a small plant with a single PLC, or meet the needs of a multi-national organization with thousands of critical devices scattered around the globe.


By deploying Tofino™ security appliances directly in front of each control device (or group of devices) that needs protection, they provide SCADA and process control companies with a layered security solution for their systems. This in turn allows a “defence-in-depth” strategy to be used, so if a hacker or virus penetrates or bypasses a main corporate firewall, they will still be faced with an array of SCADA-focused security devices that need to be breached before any damage can be done.
