It carries 28 I/O points in a 144 x 110 x 60.5 mm housing – 8 digital inputs (24 V AC/DC, sink/source), 8 analog inputs configurable by pair for NTC, PTC, Pt1000, 0-10 V, or 4-20 mA, 4 analog outputs (two voltage, two voltage/current/PWM at 2 kHz), and 8 relay outputs mixing SPDT and SPST forms, each rated 3 A. The backlit 128 x 64 LCD gives local readout without a separate HMI, and the built-in RTC drifts under 30 s/month across the -20 to 65 °C operating range. Communication ports: one CAN terminal block, two RS485 screw terminals for Modbus serial or BACnet MS/TP, plus a USB mini-B device port for programming. Power from 24 V AC or 20-38 V DC draws 12 W max. Overvoltage category II, pollution degree 2, IP20. ## Compliance and certifications Certified to relevant safety and EMC standards. Complies with 2014/30/EU and 2014/35/EU directives. Material rating UL94 V-0.","metaTitle":"Schneider TM172ODM28R Modicon M172 Controller, 28 I/O","metaDescription":"Schneider TM172ODM28R Modicon M172 programmable controller – 28 I/O, backlit LCD, CAN/RS485 ports, HVAC application.
