Ethernet port supports Modbus TCP and BACnet IP with an embedded webserver; two RS-485 ports handle Modbus serial or BACnet MS/TP. Also includes a CAN port, USB host and device ports. Runs on 24 V AC/DC ±10% AC / 20–38 V DC, drawing 15 W at full load. Backlit LCD (128×64) gives local status without a separate HMI. ## Fit and environment Panel-mount with optional DIN-rail adapter; IP20, pollution degree 2, overvoltage category II. Operating range -20 to +60 °C, 5–95% RH non-condensing, altitude to 2000 m. Dimensions 144 mm wide × 110 mm tall × 60.5 mm deep. ## Compliance documentation Meets EN/IEC 60730 for automatic electrical controls, UL94 V0 for flammability, and complies with Low Voltage Directive 2006/95/EC and physical agents (noise) directive 86/188/EEC. ## Sourcing reality Current production—no last-time-buy or end-of-life notice on this order code.","metaTitle":"TM172PDG28R Modicon M172 Controller, 28 I/O, LCD","metaDescription":"Currently active production. 28 I/O (8 DI, 8 AI, 4 AO, 8 DO), backlit LCD 128x64, Modbus TCP, BACnet IP.
