What it is and what drives the fit
The Schneider TM173ODM22RH is a Modicon programmable controller for HVAC and pumping, with 22 total I/O: 6 digital inputs, 5 digital outputs, 7 analog inputs, and 4 analog outputs. Runs on 230 VAC, draws 10 W.
Compliance and sourcing posture
This controller carries multiple standards: IEC/EN/UL 60730-1 and 60730-2-9 for automatic electrical controls, plus EMC directives 2014/30/EU and Low Voltage Directive 2014/35/EU. The material is UL94 V0. Pollution degree 2, overvoltage category II. For a procurement file, the standards list covers most project compliance checklists without separate qualification.
Mounting and physical fit
Panel-mount with optional DIN-rail accessory. Dimensions: 110 mm high, 72 mm wide, 60 mm deep. The width (72 mm) fits a standard DIN-rail slot; depth (60 mm) clears most shallow enclosures. IP20 rated. Storage temperature -30 to 70 °C; operating -20 to 65 °C, which covers most mechanical rooms. Connections: 1 CAN port, 2 RS485 Modbus serial links, 1 USB-C, a display port for the local LED, and a communication module slot. The RS485 ports are screw-terminal blocks, so no special crimp tool needed for field wiring.
