Allen-Bradley 1746-IV16 SLC 500 Digital DC Input Module, 16 Points, 24V DC Source
Allen-Bradley 1746-IV16 is a 16-point digital DC input module for the SLC 500 family, sized for 24V DC current-sourcing sensors..
Overview
The module provides 16 current-sourcing inputs in the 24V DC voltage category, operating from 10-30V DC. Signal delay is 8 ms maximum in either direction, and the backplane draws 0.085 A at 5V DC with no 24V DC load. Heat dissipation totals 3.6 W (0.2 W per point). A removable terminal block is included, and the module occupies a single 1746 I/O chassis slot.
