Relays 2-Channel Duel-Leak Detector

The PC-102 series is a dual-channel switch that provides dual protection against seal failures and over-temperature in submersible pumping applications. The relays have two form-C isolated output relays and two LEDs, which illuminate when each associated output relay is energized. The sensitivity adjustment (4.7k-100kOhms) allows you to define the input impedance at which the output relays will change state. The sensitivity for the over-temperature detector can be set to 4k Ohms with use of the DIP switches.
