The MTL4500 Series of modules and accessories is designed for use with process connected systems.
It consists of compact isolating interface modules mounted on backplanes, which carry safe-area
signals and power supplies. Hazardous-area circuits connect to the blue terminals on the modules.
Backplanes can be integrated into a user’s process system architecture or mounted in separate
The MTL4501-SR enables a fail-safe switch/proximity detector located in the hazardous area to
control an isolated fail-safe electronic output. It provides line-fault detection (LFD) alarm contacts
and is designed for use with approved fail-safe sensors in loops that require operation up to SIL3
according to the functional safety standard IEC 61508.
Note: For reliable, long-term operation the load on the LFD switching relay should not be less than
50mW, e.g. 10mA at 5V DC.

Each module has a multi-pin connector in its base that plugs into a matching connector on the backplane. This connector carries all appropriate safe-area circuits and power supplies. Additional multiway connectors, located at the front of the module, accept the wiring from the hazardous-area circuits. All connectors are keyed so that connections cannot be made the ‘wrong way round’. Status LEDs and configuration ports (where appropriate) are located on the front of the modules for easy access, and full dc isolation is provided between the input and output so that the modules are intrinsically safe without needing an earth.
MTL4500 series standard backplanes, with quick-release clip connectors, accommodate 4, 8, 16 or 24 modules. The backplane carries the safe-area signals and distributes dual-redundant 24V dc power supplies with three-point status monitoring. In applications where a number of 8- and 16-way backplanes are installed, the power supplies can be interconnected. Optional earth-rail kits are available for 8- and 16-way backplanes and tagging-strip kits are available for all backplanes.
