Product details

I/O configuration and ratings

This expansion module provides 22 total I/O points: 6 digital inputs (sink or source, 12-24 V DC), 6 digital outputs (1 open collector + 5 relay, relay rated 2 A), 5 analog inputs (voltage 0-10 V, 0-5 V ratiometric, NTC, current 0-20/4-20 mA), and 5 analog outputs (3 voltage 0-10 V, 2 PWM/PPM at 20 kHz, 12 V, 35 mA). It draws power from a 12-24 V DC supply. Two dedicated sensor supply outputs are provided: 12 V DC at 85 mA and 5 V DC at 20 mA.

Mechanical fit

Physical dimensions: 2.8 in wide, 3.4 in high, 2.4 in deep. Panel mounting compatible with DIN rail or screw fixing within the Modicon M171/M172 enclosure.
