The TM2AVO2HT is a 2-channel analog voltage output module for the Modicon M238 logic controller, delivering ±10 V outputs with 11-bit plus sign resolution. Each channel carries a total error of +/-1 %FS and a repeat accuracy of +/-0.1 %FS. The module requires an external 24 V DC supply (19.2...30 V range) in addition to 5 V DC from the backplane, drawing 60 mA on each rail. Output ripple is held to ≤1 LSB, and conversion time is 2 ms plus one controller cycle. Insulation between I/O and internal logic uses a photocoupler rated at 2500 V dielectric strength.
