Siemens 6ES7131-7RF00-0AB0 is an ET 200iSP electronic input module that provides eight NAMUR digital inputs for the SIMATIC ET 200 I/O system. It supports 8 DI NAMUR, enabling direct connection of NAMUR sensors in hazardous environments. The unit carries explosion protection ratings: Ex ib (ia Ga) IIC T4 Gb, Ex ib [ia IIIC Da] IIC T4 Gb, Ex ib [ia] I Mb, allowing safe use in gas and dust zones; Ex ib protection is designed for intrinsic safety and multiple hazardous-area embodiments. The module is intended as a digital input submodule for ET200iSP and plugs into TM-IM/EM or TM-EM/EM terminal submodules to interface NAMUR sensors (including both switched and unswitched mechanical contacts) within distributed I/O configurations.
