The Allen-Bradley 1771-IQ is a DC selectable input module designed for use within the classic Allen-Bradley PLC-5 and 1771 I/O chassis environments. This robust industrial module features eight switch-selectable inputs configured to support either current sourcing or current sinking applications, accommodating both high-true and low-true logic structures. Ideal for complex automation tasks, the 1771-IQ offers versatile filtering options with switch-selectable input delays, allowing engineers to switch between normal operational modes and fast response configurations depending on specific application demands.
Engineered for reliable performance in demanding factory floor environments, the module handles a customer supply voltage range of 5VDC to 30VDC. Configuration switches located on the hardware must be set prior to installation in either a Series A or Series B 1771 I/O chassis backplane. Its flexible design simplifies integration into legacy control architectures requiring adaptable discrete signal processing.

Ensure all power to the 1771 I/O chassis is turned off before inserting or removing the module to prevent electrical shock or equipment damage.
Set the internal hardware switches for logic definition (high/low true) and input delay times prior to mounting the module into the chassis.
Securely seat the 1771-IQ into the designated slot of the Series A or Series B 1771 I/O chassis and fasten retaining screws.
Connect field wiring to the corresponding swing-arm connector associated with the 1771 I/O chassis slot.
