Product details

Controller Overview for HVAC and Pumping Applications

The TM172PBG42R is a current-production Modicon M172 programmable controller built for HVAC and pumping solutions. Its 42 mixed I/O include 12 configurable analog inputs and multiple communication options—Ethernet Modbus TCP/BACnet IP, dual RS485 for Modbus serial or BACnet MS/TP, and USB—making it a fit for building management and pumping station controls.

I/O Configuration and Field Wiring

The 12 discrete inputs accept 24 V AC/DC and are configurable sink or source. Relay outputs are split across groupings: five SPST with a common, two SPST independent common, two SPDT same common, and three SPST independent common. Each SPST relay is rated 3 A, SPDT at 1 A. Analog outputs include four 0–10 V and two that can be 4–20 mA, 0–10 V, or 2 kHz PWM.

Power, Mounting, and Environment

Runs on 24 V AC/DC (±10%) drawing 15 W. Rated IP20, pollution degree 2, with an operating range of -4 to 140 °F (-20 to 60 °C). The built-in real-time clock holds at -4…140 °F (-20…60 °C).
