The remote signalling board is a contact interface for signalling PV 
messages and controlling PV units. It is supplied as an option for 
the AEG PV system and is intended for installation in the PV unit. 
The remote signalling master board consists of 5 potential-free 
signalling contacts and one control input.  
There is an independent 24 VDC power supply for the control in-
put. The control signal is activated by bridging the relevant input. 
There is no need for an additional auxiliary power supply.  
The signals are assigned as standard or can be configured on a 
customer-specific basis. An integrated service switch enables 
maintenance work on the unit to be signalled. 

Technical data: 
The maximum load for the signalling contacts (X3/X4) is 500 V/8 A 
AC or 50 V/2 A DC.  
 

If the specified power has been applied to the relay con-

tacts once, those contacts can no longer reliably switch 

an extra-low voltage (evaporation of the gold alloy)! 

 
The control input (X5) has an independent 24 VDC power supply. 
The input is activated via a bridge.
