Product details

Overview

The TM171OBM14R is a Schneider Modicon M171/M172/M173 optimized blind controller with 14 mixed I/O: 5 analog inputs (NTC, Pt1000, 0-20/4-20 mA, 0-1/0-5/0-10 V ratiometric), 5 analog outputs (0-10 V, PWM/PPM, 0-20/4-20 mA), and 4 digital outputs via volt-free relay contacts rated 2 A. It runs on 100-240 V AC supply, draws 85 mA at 12 V DC, and communicates over a built-in RS485 Modbus serial link plus an expansion bus for LAN modules. Schneider lists the TM171OBM14R as active production — no end-of-life notice.

I/O comparison vs TM171OBM22R

Compared to the TM171OBM22R, the TM171OBM14R trades discrete I/O for a lower channel count: 2 discrete inputs vs 6, and 4 digital outputs vs 6, while keeping the same 5 analog inputs and 5 analog outputs. The TM171OBM22R adds 6 digital inputs and 2 more digital outputs, making it the right choice when a panel needs more on-off sensing and relay switching; the TM171OBM14R fits when analog measurement density outweighs discrete count.
