Description
Product Description
The Allen-Bradley 1771-IVN is a 32-channel digital DC input module engineered for PLC-5 automation systems and Bulletin 1771 I/O chassis platforms. Designed for low-true input operation, this module interfaces with field devices operating within a 10 to 30 Volts DC range and is optimized for applications requiring reliable high-density discrete input processing.
The module supports sourcing-type inputs and is intended for use with sinking field output devices. It features four isolated groups of eight inputs, enabling flexible wiring and signal organization in distributed control architectures. The 1771-IVN operates using half-slot addressing without limitations and can also support single-slot addressing configurations depending on processor and chassis compatibility.
Built for rack-mounted installation, the module communicates directly through the PLC-5 backplane and consumes minimal backplane current, making it suitable for legacy modernization projects and existing 1771-based control systems.
