Specification

SEODescription

The Allen-Bradley 1784-PCC1 is a PLC-5 Communication Module designed as a DH+/DH485 Adapter, enabling seamless connectivity between a computer and PLC-5 systems. It features a single RS-232 port to interface with DH+ (Data Highway Plus) or DH485 networks, supporting up to 32 nodes per network for robust industrial communication. Operating within a 5V DC supply and a temperature range of 0–60°C, this module is ideal for manufacturing automation, process control, and legacy system integration. Its key strengths include reliable data transfer and compatibility with older PLC-5 architectures, though it lacks modern Ethernet/IP support and may require additional adapters for contemporary setups. The 1784-PCC1 remains a critical tool for maintaining legacy industrial networks.
