Allen-Bradley 1794-IB32 FLEX I/O 32-Point 24V DC Digital Input Module
Allen-Bradley 1794-IB32 is a FLEX I/O digital input module with 32 current-sinking 24 V DC inputs, packing high-density discrete sensing into a single terminal-base slot.
Overview
The 1794-IB32 accepts 32 current-sinking sensor signals from 19.2 to 31.2 V DC (24 V DC nominal). With a nominal input current of only 4.1 mA per point and 22.2 kΩ input impedance, it keeps the field power supply lightly loaded while the FLEX I/O adapter broadcasts point status across the FlexBus. It mounts on a DIN rail terminal base such as the 1794-TB32 or TB32S.
