Siemens 6ES7131-7RF00-0AB0 Digital Input Module

Siemens SIMATIC ET200ISP Digital Input Module 6ES7131-7RF00-0AB0 is an 8-channel NAMUR digital input module designed for the ET200iSP decentralized peripheral system, enabling NAMUR-sensor signaling in hazardous environments. Each of the eight inputs supports NAMUR transducers and includes a green status LED to aid quick diagnostics. The module carries intrinsic-safety approvals Ex ib (ia Ga) IIC T4 Gb, Ex ib (ia IIIC Da) IIC T4 Gb, and Ex ib (ia) I Mb, making it suitable for installation in hazardous locations. As part of the ET200 family, it provides a compact digital input interface for NAMUR field devices and is commonly used in process control and automation tasks requiring robust, intrinsically safe signaling.
