Product details

Overview

The TM172PDG28S is a Modicon M172 programmable controller with 28 I/O points: 8 digital inputs, 8 analog inputs, 4 analog outputs, and 8 digital outputs. It runs on a 24 V AC/DC supply and carries CE, cURus, and CSA certifications.

I/O comparison vs TM172ODM28R

Compared to the TM172ODM28R, the TM172PDG28S offers 8 analog inputs configurable by pair versus 2 analog inputs on the TM172ODM28R, and 4 analog outputs versus 5. The TM172PDG28S also lacks a high-speed counter present on the TM172ODM28R. For applications needing more analog sensing, the TM172PDG28S is the better fit; for high-speed counting, the TM172ODM28R is required.

Power and mounting

The controller draws 5 V DC 50 mA from the controller bus and 24 V DC 150 mA from the supply. It mounts on DIN rail or panel with accessory, and measures 144.78 mm wide by 109.22 mm high by 60.96 mm deep.
