TM2DDI16DT is a digital input expansion module for Schneider Electric's TM2 line (including Modicon M238 and Twido controllers), providing 16 channels of 24 VDC inputs. Each channel draws 7 mA at 24 VDC and the unit ships with a single removable screw-terminal block for wiring. The module supports sink/source configurations and connects to the TM2 expansion interface to extend a controller’s input capability.
