That mix maps directly to a pumping or HVAC control panel – sensor feedback, actuator drives, and a handful of discrete alarms. Built-in real-time clock holds drift to ≤30 s/month over the -20…65 °C operating range, enough for time-stamped trend logging without an external time source. Communication ports (1 CAN socket, 2 RS485 Modbus, 1 USB-C for program download) cover the usual fieldbus topology. The 1 MB flash / 380 kB RAM handles moderate logic and data logging. ## Physical footprint and mounting Width 2.8 in (72 mm), height 4.3 in (110 mm), depth 2.4 in (60 mm). Mounts on DIN rail via an accessory or directly to a panel. IP20 enclosure – keep it inside the cabinet away from dripping water. No forced-air cooling required at the 10 W dissipation.","metaTitle":"Schneider Modicon M173 TM173ODM22R Programmable Controller,","metaDescription":"TM173ODM22R Modicon M173 programmable controller for HVAC/pumping. 22 I/O, 6 DI, 5 relay outputs, 7 AI, 4 AO, Modbus, CAN.
