About the Allen-Bradley 1746-ITB16
The 1746-ITB16 is an SLC 16 point digital input module, now discontinued. Its 16 inputs take 24V DC, with an operating range of 10 to 30V DC and a nominal input current of 8 mA at 24V DC. Off-state is 5V DC and 1.5 mA maximum.
What is the 1746-ITB16 used for?
It brings 16 fast 24V DC signals into an SLC 500 system: the maximum signal on delay is 0.30 ms and the maximum signal off delay 0.50 ms. It draws 50 mA at 5V and 0 mA at 24V from the backplane.
Lifecycle and successor
Discontinued (Rockwell Automation lifecycle status, checked 24 October 2026).
