Wire the Alarm Relay
A 3-position terminal block labeled RELAY on the front panel of the
module provides you with a means of communicating the status of the
power supply to some alarm device. The contacts on the relay are rated at 1
Amp, 250V ac maximum. The relay energizes within 0.5 seconds after
sufficient input power is applied and no error conditions have been
encountered. The error conditions include 5V output overvoltage,
undervoltage, or overcurrent and internal reference error. The relay
de-energizes within 10 seconds following detection of an error condition or
loss of power. Contact bounce may occur for 100 ms.
