PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1771-IQC is an 8-point DC selectable Digital Input Module for the PLC-5 system. This Bulletin 1771 hardware operates within a rated voltage range of 5 to 30V DC. It provides signal conditioning for eight discrete field input devices.
The module integrates directly into 1771 I/O chassis assemblies. It supports 1/2-slot, 1-slot, and 2-slot I/O addressing configurations across the rack. Internal selector switch support enables flexible configuration for connected field signals. The unit weighs approximately 1.00 lb (0.45 kg) for standard chassis mounting.
