Schneider Electric AS-B872-200 Analog Voltage Output Module

Schneider Electric AS-B872-200 Analog Voltage Output Module is a four-channel PLC output module for Modicon 800 Series racks, delivering selectable 0–10V, ±10V, 0–5V, or ±5V analog outputs per channel. It provides 12-bit resolution with typical accuracy of ±0.1% at 25°C and an update time of under 1 ms across all channels, while offering channel-to-channel and channel-to-case isolation up to 1000 V. The unit is powered from a +5V DC supply (about 750 mA) and mounts on the Modicon backplane in rack assemblies. Applications include analog control tasks such as valve positioning, motor speed control, and process regulation in PLC-based control panels, and it is commonly used as a replacement in systems alongside Schneider AS-B872-002, Modicon 140ACO02000, and Allen-Bradley 1756-OF6VI.
