MTL 4500

Improving upon the widely adopted, enormously successful, "industry standard" MTL4000 range was a big challenge but the innovative MTL4500 range includes several new features for backplane mounting isolating interfaces. This new family easily integrates with the I/O equipment of all major instrumentation and DCS suppliers in the same secure manner as its predecessor.

 product image

The MTL5500 range modules are versatile yet simple to apply; use the latest technology and yet are well proven.

These contrasting attributes stem from the progression of our expertise in the design and manufacture of isolators for intrinsic safety and the application of innovative technology to achieve the required separation and segregation of the circuits.

The MTL5500 (DIN-rail mounting) and MTL4500 (backplane mounting) isolators share a common design, differing only in the mechanical mounting and connection methods.

MTL7700 range

The MTL7700 range follows closely in the footsteps of the MTL700 but as a DIN rail mounting barrier providing quick and easy installation without the need for special hardware. Removable terminals are used for ease of installation, maintenance and for providing a loop disconnect by simply unplugging the terminals from the side of the module. Wire entry is also angled to assist wiring within limited space enclosures. MTL7700 barriers clamp simply and securely onto standard T-section DIN rail, simultaneously making a reliable IS earth connection. For applications where field power is required for switch inputs or 2-wire transmitters, the MTL7700 range provides a bussed power feed facility. When used in conjunction with the MTL7798 power feed module the user has a fully protected, electronically fused supply to many barriers with no additional wiring required.

MTL4600 range

Building on the base of the MTL4500 range, MTL4600 range offers a high level of signal isolation for installations where multiple loops on a common connection are not desirable.

Signal isolation provides excellent protection against surges, common faults and noisy environments. It also eliminates the risk of earth loops between different areas of the plant, which, if not isolated, can cause significant errors or failures under fault conditions.

MTL4600 isolators are fully compatible with all existing backplanes used with the MTL4500 range and many control systems. The form factor and signal types offer the user a common approach for both IS and non-IS signals.
