Product Overview

The 1785-L20C15 is an Allen-Bradley PLC-5 series processor module integrating ControlNet communication. It functions as a ControlNet-enabled programmable controller (PLC-5/20C15) that supports both scheduled and unscheduled peer-to-peer communication across a ControlNet network. Installed in a PLC-5 rack, it coordinates local and networked I/O including remote, analog, and universal remote I/O, and maintains program and data integrity via battery-backed RAM and optional EEPROM modules. Typical deployment includes distributed process control systems, machine automation with high-speed networked I/O, and redundant ControlNet installations.
