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 MTL4511 contains a changeover relay, which enables a safe-area load to be controlled by a
switch or proximity detector located in a hazardous-area. When selected, the line-fault detect (LFD)
facility detects open or short circuit conditions in the field wiring and also indicates this on the top of
the module. Line-Fault Detect and Phase Reversal for the channel are selected by DIL switches
on the side of the module and output is provided by the changeover relay contacts.
Channel 1 only switch settings apply.
For switch sensor inputs, with LFD selected, make sure resistors (22kΩ and 680Ω) are fitted.
Note: For reliable, long-term operation the load on the output switching relay should not be less
than 50mW, e.g.10mA at 5VDC.

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.
