Output Test Pushbutton
A relay with style number xxx-xxx-xxCxx is equipped with a momentary-action pushbutton accessible
through the front panel. When pressed, the switch energizes the main and auxiliary output relays. To
prevent accidental relay tripping, the pushbutton is recessed behind the front panel. The button is pressed
by insertion of a thin, non-conducting rod through the button access hole in the front panel.
Power Supply
Relay operating power is developed by a wide-range, isolated, low-burden, switching power supply that
delivers
±
12 Vdc to the relay’s internal circuitry. The power supply is not sensitive to the input power
polarity. A front panel LED power indicator lights to indicate that the power supply is functioning properly.
Style number designations and input voltage ranges for the available power supply models are provided
in Section 1,
