SHORT CIRCUIT ISOLATOR

VDOT-SCI Short Circuit Isolator is a short circuit isolator module that prevents an entire loop failure in the event of a short in the loop.

If a short is detected the yellow LED indicator illuminates, and the short circuited area is isolated automatically.

Upon removal of the short condition, the module automatically connects the area to restore the entire loop to the normal operating status.

This module is not addressable.
