RTK Series UC625 Annunciator
37
Higher Voltage Powered Inputs
If specified at the time of order RTK can supply the unit suitable for use with high voltage signal
inputs there are 3 options available
•
48VAC/DC
•
110VAC/DC
•
250VAC/DC.
Fuse F1 on the rear of the annunciator is used to protect the H.V. signal supply.
+VC is internally linked to ALL of the “C” terminals within the annunciator.
The “C” terminal is provided for Customer use to distribute the + H.V. signal supply to the associated
field contacts.
The user is able to wire a powered Input direct to the associated input terminal as long as the OV of
the Customers supply is connected to terminal OVC on the UC625 annunciator.
Terminal OVC is internally linked as a common return for all channels.

Important note:-
In standard UC625 Models RTK p24VDC as a signal supply voltage and this voltage is
available if either the primary or aux supply are present on the annunciator.
If the Customer is using an external H.V. signal supply this supply must be available for use when
either the primary and aux supply is available for the unit to function correctly.
