Power supply unit board and relay board

The combined power supply unit and relay board provides the entire voltage supply as well as the 13 Relay
outputs for control and status functions of the Extinguishing Control Computer 8010. The 230V AC mains
voltage must be connected to the appropriate terminals on the housings rear side and must NOT be connected
to the power supply and relay board in the panel. An increased current requirement e.g. as a result of longer
cable lengths, must be compensated for if necessary by an external voltage supply via a separate power supply
unit.
The power supply of the Extinguishing Control Computer 8010 is monitored continuously of:
•
Mains failure
•
Battery charge
•
Battery charge, current limited
•
Earth fault identification (insulation)

Terminals
The power supply and relay board is internally wired with the 50-pole D-SUB plug to connect the external
terminal card with the relay terminals 1 to 11 and both terminals of the mains voltage relays 12 and 13 at the
housings rear side.
Relay outputs
The power supply unit and relay board of the Extinguishing Control Computer provides 13 relay outputs for
switching and control functions. Status functions such as faults, deactivations, common fire or others of the
possible switching conditions can be assigned to the relays, whereby an OR logic operation of the individual
functions can also be programmed. All relay outputs are protected with separate melting fuses. The activation
time and the duration of each relay is programmable with the programming software.
