The Schneider TM171VEVM4 is an active Modicon M171 controller running on 24 V +/-10% AC/DC. It packs 8 mixed I/O — 4 analog inputs (NTC, Pt1000, 4-20 mA, or 0-5/0-10 V), 2 digital inputs (sink/source), and 2 digital outputs (1 open collector, 1 SPST relay). A single Modbus RS485 port handles the serial link. No display, so it's a pure controller for embedded or cabinet-mount jobs. Dimensions are 2.8 in (70.2 mm) wide, 3.4 in (87 mm) tall, 2.4 in (61.6 mm) deep — fits a standard DIN rail footprint. IP20, so it expects a clean indoor panel. CE marked for EU compliance.
