The 350 relay is equipped with eight (8) contact inputs, which can be used to provide a
variety of functions such as for circuit breaker control, external trips, blocking of protection
elements, etc. All contact inputs are wet type contacts (refer to the 350 typical wiring
diagram) that require an external DC voltage source. The voltage threshold (17V, 33V, 84V,
166V) is selectable, and it applies for all eight contact inputs.
The contact inputs are either open or closed with a programmable debounce time to
prevent false operation from induced voltage. Because of de-bouncing, momentary
contacts must have a minimum dwell time greater than half power frequency cycle. The
debounce time is adjustable by the user.
