ld-harvest Main control board

More about the product

The main control board receives and processes control commands from the human-machine interface and PLC through the serial (parallel) port or interface board, and sends its own status information to the outside. The main control board also generates trigger pulses for each phase of the power unit, collects and processes the fault information fed back by all power units, notifies the human-machine interface to record the fault, and notifies the PLC to implement system alarms and protection.
