Remote I/O module, IP20, Safety, SIL power supply - UR20-PF-O-2DI-SIL

Weidmüller UR20-PF-O-2DI-SIL is a safety power feed module for the u-remote system: it opens a new output current path (I_OUT) segment and allows that segment to be switched off in a safety-related manner, feeding up to 8,050 mA. Unlike the plain UR20-PF-O, it carries two digital inputs for the safety switching signals and is qualified for functional safety use with a hardware fault tolerance of 1 and a safe failure fraction of 98 %. Use it where a group of output modules must be de-energised as part of a safe shutdown while the rest of the station keeps running.

• Function: Safety power feed — starts a new output current path (I_OUT) segment with safety-related shutdown
