Figure 7.9.1-5 Trip circuit supervision using one of the VAMP 200 series
internally wetted digital input (DI1...DI6) and auxiliary relay K1 and an
external resistor R. The circuit-breaker is in the closed position. The
supervised circuitry in this CB position is double-lined. The digital input is
in active state when the trip circuit is complete.
Figure 7.9.1-6 An example of digital input DI1 configuration for trip circuit
supervision with one wet digital input.
Figure 7.9.1-7 An example of output matrix configuration for trip circuit
supervision with one wet digital input.
