About the Allen-Bradley 1746-IN16

The 1746-IN16 is an SLC 16 point 24V AC input module, discontinued on 8/31/2018. Its 16 inputs take 10…30V AC or 10…30V DC, with a nominal input of 8 mA at 24V DC or 24V AC and an inrush current of 0.02 A (AC only) (selection guide 1747-SG001). Off-state values are 3.0V and 1 mA, and it draws 85 mA from the backplane.

What is the 1746-IN16 used for?

It brings 16 low voltage signals, AC or DC, into an SLC 500 system. The signal on delay is 15 ms max on DC and 25 ms on AC.
