Packaged in the SIPLUS variant, it carries 2 current-sinking digital inputs (24 V DC) and 2 solid-state digital outputs (0.5 A each). Switching is fast—2 µs on and 10 µs off—and the module supports parameterisable inputs, diagnostics, and alarms. Power loss is a lean 1 W typical, and the module draws 4 mA per channel from the backplane bus at 5 V DC.
