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 MTL4524S enables an on/off device in a hazardous area to be controlled by a volt-free contact
or a floating logic signal in the safe area. It can drive loads such as solenoids, alarms, LEDs and
other low power devices that are certified as intrinsically safe or are classified as non-energy-storing
simple apparatus. Short-circuit the Control input terminals to switch the output on.
A second safe-area voltage input (Override) is provided. With 9– 24V applied the Control input is
enabled; when below 2V it forces the output to the off state.
Note: The Control input must be from an isolated source with respect to the Override input. The
Override + (terminal 8) is joined internally to the Control – (terminal 11).

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.
