The Siemens 6ES7131-7RF00-0AB0 is a DP electronics submodule for the ET200iSP distributed I/O system, delivering eight NAMUR digital inputs (8 DI NAMUR) to feed NAMUR signals into the SIMATIC DP network in an ET200SP rack. It carries intrinsic safety approvals for hazardous environments, including Ex ib [ia Ga] IIC T4 Gb, Ex ib [ia IIIC Da] IIC T4 Gb, and Ex ib [ia] I Mb. As part of the SIMATIC DP family, this module interfaces directly with the DP bus to bring eight NAMUR-compatible DI signals into the ET200SP, with a documented standby current specification of up to 1.2 mA for a resting input.
