The TM171EP14R is an additional I/O module for the Modicon M171/M172 controller range, providing 14 mixed I/O points: 4 digital inputs (24 V AC/DC, sink or source logic, 2.5 mA draw), 4 analog inputs configurable by pair for voltage (0...10 V, 0...5 V ratiometric), current (4...20 mA), or NTC/PTC temperature probes, 2 analog outputs (voltage 0...10 V), and 4 relay outputs (one SPDT with independent common, three SPST with shared common, each rated 3 A). A single CAN port on a screw terminal block serves as the expansion bus connection. Rated supply is 24 V.
