DC OK signal instruction:

Provide alarm function when power source is abnormal. Clients can quickly know whether power source is abnormal or not by the relay contacts are open circuit or short circuit. We call these contacts as DC OK signal contacts.

Power source abnormal definition:

Voltage alarms when output voltage value is not in the range of -10% to +10%, open circuit for relay.

Current alarms when output current value is over 100%, open circuit for relay.

Temperature alarms when monitor panel temperature is lower than -20 or higher than 75 degrees Celsius, open circuit for relay.

Relay alarm is normally closed contact. (For the two contacts, short circuit when power source is normal; open circuit when power source is abnormal.)
