Relay output circuit
①
Direct-current power supply
②
Emergency stop: An external switch is used.
Fuse: To protect the output circuit, a fuse having a breaking capacity in the range of 5 A to 10 A is connected to
③
the common terminal.
④
Alternating-current power supply
A relay or a solenoid valve is used as a DC load. A diode is connected in parallel to absorb the surge voltage
which occurs when the load is OFF.
