4.2.2.6. Dry Contacts ( On optional interface card )
There are 4 dry contact sockets on the Inteface Board. The relays can be programmable from RELAYS
menu (under SETTINGS menu). “Bypass Active, General Alarm, High Temperature, Synchronization
OK, Battery Test Failure, Output Failure, Input Failure” alarms can be assigned to these contacts. Each
alarm can be assigned to separate contacts but also one alarm may be assigned to multiple contacts.
Each output socket 3-pin and middle pin is fixed, the upper pin is normally closed and lower pin is
normally open. The maximum values of the relays is 250VAC 5A.
Free contact relay connection cables shall have a cross-section of 1.5 mm
2
.
Maximum voltage to be applied to the relay contacts is 42V AC rms (sinus) or 60 Vdc.
Maximum contact current depends on the applied voltage and the load characteristic. Both
maximum voltage and maximum contact current corresponding to the applied voltage shall
not be exceeded.
