DBB02DM24 Carlo Gavazzi

DBB02DM24, True Delay to Disconnection Timers Models DBB02, PBB02, DBB02DM24, True Delay to Disconnection Multivoltage Relay with 3 time scales, from 60 s to 10 h, selectable by DIP switches. The built-in battery (NiCd) will be charged while the power voltage is connected. For DIN rail mounting- (DBB02) or plug-in module (PBB02)., DBB02DM24, The relay (the relays) connects (n) when applying the supply voltage. When the supply voltage is interrupted, the time period begins, and when the time period ends, the relay disconnects. If the supply voltage is reconnected before the relay disconnects, the time will be zeroed and the relay will stay connected. The built-in battery (NiCd) will be charged while the supply voltage is connected. Note: DBB02 and PBB02 must not operate using pulses smaller than 200 ms. In this case, the DMB01 or PMB01 relays, operated by external contact, must be used. The battery test will be performed on terminals + and A2 or 7 and 10. It is recommended to have the DBB02 and PBB02 equipment connected to the power supply for 42 hours before their entry into service to compensate for the loss of energy due, for example, to a long storage period.
