This is a Schneider Modicon Quantum 140SDO95300S safety DC discrete output module — 16 source outputs, 19.2…30 VDC, each group rated to 10.04 A. It's the safety-rated version of the standard Quantum DO, with a response time ≤20 ms state 1→0 and internal fault detection (overload, power supply, channel). The formula on the label for load inductance (L = 0.5 / (I² × f)) tells you it's designed for inductive switching at low frequency — expect solenoids, contactors, valve coils.
The module draws 350 mA from the Quantum backplane and addresses 4 output words plus 7 input words. Isolation between groups and bus, and between channels and bus, is 1500 Vrms for 1 minute.
