SIL 2 Switch/Proximity Detector Repeater Transistor Out


The dual channel Switch/Proximity Detector Repeater D5037D module is a unit suitable for applications requiring SIL 2 level (according to IEC 61508:2010 Ed. 2) in safety related systems for high risk industries.
The unit can be configured for switch or proximity detector (EN60947-5-6, NAMUR), NO or NC and for NO or NC optocoupled open collector transistor output.
Each channel enables a Safe Area load to be controlled by a switch, or a proximity detector, located in Hazardous Area.
A fault detection circuit (DIP switch configurable) is available for proximity sensor and switch equipped with end of line resistors. In case of fault, when enabled it de-energizes the corresponding output transistor and turns the fault LED on; when disabled the corresponding output transistor repeats the input line open or closed status as configured.

Mounting on standard DIN-Rail, with or without Power Bus, or on customized Termination Boards, in Safe Area or in Zone 2.


• Systematic capability SIL 3
• Input from Zone 0 (Zone 20), installation in Zone 2
• NO/NC switch/proximity Detector Input, NO/NC transistor driving mode.
• Field open and short circuit detection.
• Three port isolation, Input/Output/Supply.
• EMC Compatibility to EN61000-6-2, EN61000-6-4, EN61326-1, EN61326-3-1 for safety system.
• In-field programmability by DIP Switch.
• High Density, two channels per unit.
• Simplified installation using standard DIN-Rail and plug-in terminal blocks, with or without Power Bus, or customized Termination Boards.
• 250 Vrms (Um) max. voltage allowed to the instruments associated with the barrier.
