Its 12 analog inputs accept NTC, Pt1000, 0-10 V, and 4-20 mA — the sensor set you find on air handlers, chillers, and pump stations. Two RS485 ports handle Modbus or BACnet MS/TP, and the Ethernet port serves Modbus TCP, BACnet IP, and a built-in webserver. Lifecycle stage is current; no end-of-life notice is on file. Analog inputs are configurable by pair; the 10 kOhm impedance is suited for 0-10 V signals, and the controller supplies 24 V at 150 mA to power external 4-20 mA transmitters directly. For long sensor runs, the 4-20 mA loop is your best noise rejecter — keep the shield grounded at one end. Digital inputs are sink or source at 24 V AC/DC, 2.5 mA per channel. Digital outputs are relays: a mix of SPST and SPDT, rated 3 A for SPST or 1 A for SPDT. That covers solenoid valves, contactor coils, and pilot lights without external interposing relays.","metaTitle":"Schneider TM172PDG42R Modicon M172 Controller, 42 I/O","metaDescription":"Current production. 42 I/O (12 analog, 12 digital), display, Modbus/BACnet/Ethernet.
