Product Description

The Allen-Bradley 1771-P4S I/O module, a key component of the 1771P4S PLC module family, supports up to 32 digital I/O points with configurable input/output allocation. Designed for integration into PLC-5 systems, it connects directly to 1771 chassis slots and interfaces via the proprietary backplane communication protocol. Operating within 10-30V DC, this robust module functions reliably in industrial environments (-20°C to 60°C), making it ideal for manufacturing, automotive, and heavy machinery applications. Its modular design enables seamless expansion with additional 1771-series modules. While lacking built-in networking interfaces, it excels in local control tasks with fast response times. Notable durability is offset by legacy technology compatibility constraints. The 1771-P4S features screw-terminal connections for simplified wiring and compact dimensions (130mm x 50mm x 120mm) for space-conscious installations.
