I have a device which has motor and circuits with PLC. This device is connected to a 12v battery which is powering the PLC and motor. Everything is working fine but when the motor's load is heavy, it draws the power from the battery and cause the PLC to shut down due to lack of power. And happened in milliseconds. My PLC will then be rebooted. This is a problem for me.
Beside having an isolated power source for PLC and motor any other ways which we can prevent the PLC from being shutting down? Is there a way to drain piority power to the plc?
