Powered Inputs @ 24VDC
If required, the standard unit can be wired to accept +24VDC customer powered inputs.
This is achieved by connecting the OV of the customers signal supply to terminal OVC on the UC625.
Terminal OVC is internally linked as a common return for all channels
+24VDC can then be used as a direct connection to the associated Input or it can be +VC and
internally linked to the common “C” terminals to signal contacts as typically shown below.

Important note:-
In standard UC625 Models RTK provide +24VDC as a signal supply voltage and this voltage is
available if either the primary or aux supply is present on the annunciator.
If the Customer is using an external signal supply this supply must be available for use when either the
primary and aux supply is available for the unit to function correctly.
