The Siemens 6ES7131-4RD02-0AB0 is an ET 200S electronics module providing 4 NAMUR digital inputs at 24 V DC in a 15 mm wide housing. It includes diagnostic alarm capability and wire-break detection for monitoring field devices. The diagnostic alarm (can be enabled) and red SF group fault LED signal a sensor circuit open or line break.
It provides 4 NAMUR digital inputs at 24 V DC in a 15 mm wide housing. Features include diagnostic alarm, wire-break detection, electronic short-circuit protection, and a group fault LED. Each input supplies 8.2 V to the sensor and draws 45 mA from the backplane.
