That covers both legacy and modern fieldbuses for most HVAC networks. Panel mount with accessory DIN rail bracket. IP20, pollution degree 2. Dimensions 5.7 in wide x 4.3 in high x 2.4 in deep — fits standard enclosure cutouts. Ambient operating temperature -4 to 149 °F (-20 to 65 °C), storage down to -22 °F. ## Analog input accuracy and sensor support Analog inputs accept NTC 103AT-2 or NK103, PTC, Pt1000, plus 0–10 V, 0–20 mA, 4–20 mA, and resistance modes. Accuracy on the 4–20 mA loop is ±1% of full scale ±1 digit — tight enough for chiller or VAV box control. Pt1000 gets ±1.5 °C from -50 to 100 °C, widening outside that band. ## Power and sensor supply Powered by 24 V AC/DC ±10%, draws 14 W. Sensor supplies: 5 V DC at 50 mA and 24 V DC at 150 mA from the controller.","metaTitle":"TM172PDG42RI Modicon M172 HVAC Controller, 42 I/O","metaDescription":"TM172PDG42RI programmable controller with 12 AI, 6 AO, 12 DI, 12 DO, backlit LCD, Ethernet, RS485, BACnet, Modbus.
