† 14 Vdc is required to start the power supply.
Relay operating power is developed by the wide range, isolated, low burden, flyback switching, solid state
power supply. Nominal ±12 Vdc is delivered to the relay internal circuitry. Input (source voltage) for the
power supply is not polarity sensitive. A red LED turns ON to indicate that the power supply is functioning
properly.
Power Supply Status Output
A normally closed output relay may be provided, whose contact remains open when energized by the
presence of nominal voltage at the output of the power supply. If the power supply voltage fails or falls
below requirements, the power supply status output relay will deenergize, closing its contact. If the power
supply status output is provided, then auxiliary output contacts are not available.
