Schneider Electric TM2AVO2HT Analog Output Expansion Module

The Schneider Electric TM2AVO2HT is a two-channel analog voltage output expansion module for Modicon M238 PLCs, enabling precise control signals (±10 V) to field devices such as variable frequency drives and process valves. It provides 2 analog voltage outputs with 11-bit plus sign resolution, powered from a 24 V DC supply (19.2–30 V DC) and drawing about 60 mA at 24 V, with 2500 V isolation between I/O and internal logic and a removable screw terminal block for easy wiring; load impedance is ≤ 3000 Ohm (resistive). As part of the Modicon M238 Expansion I/O family, it is compatible with Modicon M238 logic controllers, Advantys OTB, and Twido systems. Common applications include manufacturing equipment, packaging machinery, conveyors, water treatment facilities, HVAC control systems, and other process control installations where PLCs must generate analog voltage outputs to regulate equipment. Common replacements include Schneider Electric TM3AQ2, TM3AQ4, and BMXAMO0210.
