4.6 Alarm Terminal Block
The device provides an alarm terminal block on the rear panel for alarm output. When the switch
works properly, the normally-open contacts of the alarm relay are closed and the normally-closed
contacts are open; when an alarm occurs, the normally-open contacts are open and the
normally-closed contacts are closed. The alarm is outputted through a 3-pin 3.81mm-spacing
plug-in terminal block.
