Product details

HVAC controller with 42 I/O

The Schneider TM172PBG42RI is a Modicon M172 programmable controller designed for HVAC control, offering 42 I/O points: 12 digital inputs (24 V AC/DC sink/source), 12 relay digital outputs (SPST/SPDT, 3 A), 12 analog inputs configurable by pair (0-10 V, 0/4-20 mA, NTC/PTC/Pt1000), and 6 analog outputs (4 voltage, 2 voltage/current/PWM). Built-in real-time clock drifts under 30 s/month across the -4 to 149 °F operating range. Communication stack includes Ethernet (Modbus TCP and BACnet IP), two RS485 ports (Modbus serial or BACnet MS/TP), USB for programming, and a CAN port. No display on this variant.

Mounts on DIN rail using an accessory (panel mount also possible). Dimensions: 5.7 x 4.3 x 2.4 in (144 x 110 x 60.5 mm). IP20 rated, pollution degree 2, overvoltage category II. Power draw is 14 W at 24 V AC/DC (20-38 V DC or 24 V ±10% AC). Digital output relay contacts rated 3 A per output. Discrete inputs are sink or source, 2.5 mA at 24 V AC/DC. Sensor power supply provides 5 V DC at 50 mA and 24 V DC at 150 mA.

Carries CE marking under EMC directive 2014/30/EU and Low Voltage directive 2014/35/EU. Material flammability rating UL94 V0. Ambient storage -22 to 158 °F, operation -4 to 149 °F (UL derated to 140 °F horizontal). Lifecycle stage is current — no discontinuation risk, no last-time buy needed for this code.

Frequently asked questions

What compliance documentation does the TM172PBG42RI meet?
