A no-voltage output and voltage output switching circuit includes an actuator connection terminal block including a plurality of ports each including a first pin, a second pin, and a third pin to which an actuator is connected, a power connection terminal block including a voltage terminal and a common terminal to which a power supply is connected, first relays, and second relays. The common terminal is connected to the second pin of each of the plurality of ports. The first relay enables connection between the first pin of a corresponding port among the plurality of ports and the third pin of the corresponding port. The second relay corresponding to the port corresponding to the first relay enables connection between the first pin of the port and the voltage terminal.
