Product Introduction
The Allen Bradley 1785-L20E/E PLC-5/20 Processor is an industrial programmable controller designed to provide reliable logic processing and integrated Ethernet communication for PLC-5 automation systems. Produced by Rockwell Automation and part of the Allen-Bradley PLC-5 controller family, this processor combines traditional PLC-5 control capability with modern network connectivity.
The module features 16K Word SRAM memory for control program storage and system data handling. In addition, it includes embedded TCP/IP communication with EtherNet/IP support, allowing the controller to communicate directly with industrial networks, engineering workstations, and supervisory systems. This capability makes the processor suitable for upgrading existing PLC-5 installations to Ethernet-based automation environments while maintaining compatibility with legacy PLC infrastructure.
