Title:
NO-VOLTAGE OUTPUT AND VOLTAGE OUTPUT SWITCHING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2018/011925
Kind Code:
A1
Abstract:
A no-voltage output and voltage output switching circuit (1) has: an actuator-connecting terminal block (2) having a plurality of ports (21a, 21b, 21c, 21d) including a first pin, a second pin, and a third pin, to which an actuator is connected; a power-supply-connecting terminal block (3) having a voltage terminal (31) and a common terminal (32), to which a power supply is connected; a first relay (4a, 4b, 4c, 4d); and a second relay (5a, 5b, 5c, 5d). The common terminal (32) is connected to the second pin of each of the plurality of ports (21a, 21b, 21c, 21d). A first relay (4a) makes the first pin (26a) of a corresponding port (21a) and the third pin (28a) of the port (21a) connectable. A second relay (5a) corresponding to the port (21a) that corresponds to the first relay (4a) makes the first pin (26a) of the port (21a) and the voltage terminal (31) of the first pin (26a) connectable.
