The PC-102 series is a dual-channel switch that provides protection against seal failures and overtemperature in submersible pumping applications. Both PC-102 units have two form-C isolated output relays and two LEDs that illuminate when each associated output relay is energized. The sensitivity adjustment (4.7–100 kΩ) allows you to define the input impedance at which the output relays will change state. The sensitivity for the overtemperature detector can be set to 4 kΩ with the use of the DIP switches.
Note: This unit may not be compatible with Flygt pumps.
