The 1785-L40C is a ControlNet-enabled PLC-5/40C processor manufactured by Allen-Bradley (part of Rockwell Automation) for industrial automation applications. Here is a breakdown of its main features and functions:
Features:
The 1785-L40C acts as the central processing unit (CPU) for the PLC-5 control system.
It reads input signals from sensors and switches connected to the system.
It is based on user-written programs that process these signals and generate control signals to actuators (such as motors, valves) to automate various industrial processes.
The ControlNet feature allows the 1785-L40C to communicate with other devices on the ControlNet network, enabling data sharing and distributed control in larger automation systems.
