The Allen-Bradley 1746-IV16 is a 24V DC sourcing digital input module designed for integration within the Allen-Bradley SLC 500 I/O chassis system. Featuring 16 sourcing input points sharing a single common, the 1746-IV16 interfaced module captures DC discrete signals from field sensors and switching devices to deliver accurate status feedback to the SLC 500 controller backplane.

Features

Equipped with 16 DC sourcing input points operating on a 24V DC voltage category.
Utilizes a single common line across all 16 channels.
Draws backplane current directly at 5V DC (85 mA) with 0 mA current consumption at 24V DC.
Features color-coded removable terminal blocks (RTB) for efficient field wiring maintenance.
Compatible with Bulletin 1492 pre-wired cable systems (1492-CABLEB) for direct interface module connection.

Applications

Digital sensor signal processing in SLC 500 industrial automation systems
Sourcing input interfaces for field switches, proximity sensors, and pushbuttons
Control panel discrete I/O rack integration
