Schneider Electric SE AS-B872-200 Output Module

AS-B872-200 is a Modicon four-channel analog voltage output module for Schneider Electric PLC systems. It provides four 12-bit D/A voltage outputs with per-channel ranges of ±10 V, ±5 V, 0–10 V, or 0–5 V. With update times under 1 ms for all four channels and isolation rated up to 1000 V (channel-to-channel, channel-to-case, and channel-to-module), it enables precise, isolated signal generation for analog actuators and instrumentation. The module occupies one rack slot and uses the AS-8535-000 terminal connector, with mechanical keying variants for housings such as AS-B873-001, and is designed for Modicon 984 and 800-series I/O backplanes. Power requirements are +5 V at up to 750 mA, +4.3 V at up to 5 mA, and -5 V at 0 mA. The unit weighs about 3 lb (1.4 kg). This combination of resolution, per-channel range configurability, fast update, and robust isolation makes AS-B872-200 well-suited for driving analog devices in industrial automation and process control environments.
