Masibus 9000Ex-41, 9000Ex-41-FS, 9000Ex-42, 9000Ex-43, 9000Ex-44 and 9000Ex-45 Switching Repeater are engineered to provide safe and reliable signal transmission from hazardous areas to non-hazardous areas. These devices are specifically designed to transfer digital signals originating from NAMUR sensors or dry contacts located in hazardous zones, ensuring that control operations in safe areas can be executed without compromising safety.

By enabling a safe-area load to be controlled by a switch or proximity detector installed in a hazardous environment, these repeaters serve as a critical interface for process automation in industries where intrinsic safety is paramount.

The design incorporates galvanic isolation between the intrinsically safe digital input, the output, and the auxiliary power supply. It have output relay, which changes state in direct response to the input signal. For ease of monitoring, the output status is clearly indicated by an Status LED located on the top of the module. This visual feedback ensures quick diagnostics and status verification during installation and maintenance.

With Line Fault Detection Output Relay, Line faults are signalled through a separate LFD relay and LFD LED indicated on the top of the module. To preventing unsafe operations, output relay is de-energized during a fault condition.

Switching Repeaters combine robust safety features with operational flexibility, making them an ideal choice for hazardous-area applications in process industries such as oil and gas, chemical, pharmaceuticals etc. The compact design with galvanic isolation, and advanced fault detection capabilities ensure excellent performance and compliance with safety requirements.
