This is the SIPLUS ET 200SP digital I/O slice, order code 6AG1138-4FA04-2AB0. It packs 8 fail-safe digital inputs and 2 digital outputs in a 30 mm wide housing—81 high, 52 deep. The inputs are parameterizable as single-channel (Cat. 3, SIL 2) or two-channel (Cat. 4, SIL 3). Response time from 0 to 1 or 1 to 0 is 0.3 ms minimum, 17 ms maximum. Powered from 24 V DC, the module draws 300 mA typical from the backplane. Power loss is 4 W, leaving headroom for additional slices on the same bus. Ambient range covers -25 to 60 °C, so it's comfortable in unheated cabinets or near hot equipment. Built-in diagnostics include a group error SF LED and diagnostic alarm reporting via the backplane.
