Relay Connection
】
This device provides 1 M12 D-Coded 4-Pin slot
(female) for relay output. R1 and R2 is a pair of
normally open contacts of device alarm relay.
They are open circuit in normal non alarm state,
closed when any alarm information occurs.
Such as: it's closed when power off, and send out alarm. This
series switches support 1 channel relay alarm information
output, support DC power alarm information or network
abnormal alarm output, it can be connected to alerting lamp,
alarm buzzer, or other switching value collecting devices for
timely warning operating staffs when alarm information occurs.
