Allen-Bradley 1734-IB4 4-Channel 24VDC Input Module

Allen-Bradley 1734-IB4 is a four-channel digital input module for the POINT I/O family that accepts 24V DC signals with sinking inputs. Each channel draws up to 5 mA and the four inputs share a common return, simplifying wiring for standard 24V sensors. Used in distributed automation, the 1734-IB4 reports the on/off state of each input to a Rockwell Automation controller via the POINT I/O backplane, making it suitable for monitoring pushbuttons, limit switches, proximity sensors, and safety interlocks in 24V DC control circuits. This compact 4-point module integrates with existing 1734 POINT I/O configurations to expand input capacity without adding complexity to panel wiring or wiring runs, delivering reliable digital input signals for ladder logic, function blocks, or structured text programming in factory automation environments.
