Allen-Bradley 1746-IV8 is an 8-point digital input module for the SLC 500 backplane that accepts 10–30 VDC sourcing signals. Each of its eight inputs shares a common terminal and draws about 8 mA at 24 V DC (nominal), making it suitable for wiring standard 24 VDC field devices such as pushbuttons, limit switches, and sensors. As part of the 1746 SLC 500 I/O family, the IV8 mounts in a 1746 backplane rack to monitor DC-level signals in industrial automation systems.
