TM2AMO1HT Schneider Modicon M238 Analog Output Module 1 Channel

TM2AMO1HT Modicon M238 Analog Output Module

TM2AMO1HT is a single-channel analog output module for Modicon M238 logic controllers. It gives one voltage or current output. The module uses a removable screw terminal block. It fits Advantys OTB and Twido ranges too.

This module turns digital values into smooth analog signals. It drives valves, drives, and meters. The 12-bit resolution gives fine control. A photocoupler isolates the channel from internal logic. The unit needs an external 24 V DC supply.
