Pump Control from Littelfuse - PC-XXX-LLC Series

 Pump Control from Littelfuse in Small Package - Octal Socket

The Littelfuse PC-xxx-LLC-CZ and PC-xxx-LLC-GM series are liquid level control relays used to control conductive liquid pumping operations in a pump-up or pump-down application. The units come in two different voltage ranges (see specs below). The units have an adjustable sensitivity knob (4.7 k to 100 k ohms) that is set according to the resistance level at which you want the probes (sold separately) to sense the conductive liquid. The units have a built-in debounce time delay that prevents the relay from energizing if the probe resistance momentarily goes above or below the sensitivity set point (due to liquid splashing in the tank). The Little Fuse units operate their internal relay based on inputs from a high and low probe and a common reference (when a conductive tank is used) or common probe (when a non-conductive tank is used).
