The TM172EVEV2B is a Modicon M172 expansion unit that adds two EEV driver bipolar outputs to an existing controller. It mounts on DIN rail, draws 30 W DC or 30 VA AC, and uses a single CAN port with a removable 3-way screw connector.
Power budget: the unit draws up to 30 W on 24 V DC or 30 VA on 24 V AC, so factor that into the supply sizing — it's a dedicated load, not backplane-powered. Supply voltage accepts 24 V +/- 10 % AC or 20...38 V DC, giving flexibility for either a transformer or regulated DC bus. Ambient operating range is -4...149 °F (-20...65 °C) with 5...95 % non-condensing humidity; storage goes to -22...158 °F (-30...70 °C), good for unheated warehouses. The single CAN port uses a removable 3-way screw terminal; compliance includes UL 60730-1, UL 60730-2-9, and material flammability UL94 V0, with overvoltage category I and pollution degree 2 for standard cabinets. Dimensions: 2.4 in (60 mm) deep, 2.8 in (72 mm) wide, 4.4 in (113 mm) tall — fits alongside other Modicon expansion slices on the same DIN rail.
