Schneider Electric 140DAO85300 Discrete Output Module

Schneider Electric’s Modicon Quantum 140DAO85300 is a 32-channel AC discrete output module designed for backplane mounting in Quantum controllers. It provides four groups of eight outputs with an output voltage range of 20 to 253 V AC at 47–63 Hz, suitable for industrial control of AC loads. Each output can switch up to 1 A RMS, for a module-wide maximum of 16 A RMS and up to 4 A per group, with addressing that requires two output words. The module features a nominal voltage drop of 1.5 V per channel, a broad absolute maximum of 300 Vrms for 10 seconds (400 Vrms for a single cycle), and a surge current capability of up to 2.5 A during 1 ms. Power dissipation is specified as 1.60 W plus (1.0 V × total module load current), and the unit draws about 320 mA from the backplane bus, weighing approximately 0.45 kg. Visual indicators include one green bus-present LED, one red external fault LED, and 32 green LEDs for per-output status, while protection is provided by an internal RC filter and a 4 A fuse on the output path. This discrete output module is intended for Modicon Quantum systems requiring reliable, backplane-driven AC output control across multiple channels, with clearly defined grouping and addressing to support scalable I/O configurations.
