5. Alarm Contacts

Both input voltages are monitored individually. If one input voltage is too low or completely lost, it will be indicated
by an alarm relay contact.

Each input has its own monitoring circuitry and relay contact.

Alarm threshold

nom.

21.5V (±0.5V)

Relay contact opens immediately after
the input voltage falls below this value
