The PC series (PC-xxx-LLC-CZ and PC-xxx-LLC-GM) is a liquid level control relay used to control conductive liquid pumping operations in a pump-up or pump-down application. These relays come in two different voltage ranges and have an adjustable sensitivity knob (4.7-100 kΩ) that is set according to the resistance level at which you want the probes (sold separately) to sense the conductive liquid. They have a built-in debounce time delay that prevents the relay from energizing if the probe resistance momentarily goes above or below the sensitivity setpoint (due to liquid splashing in the tank). These 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).
Note:
•PC-xxx-LLC-CZ is compatible with Crouzet’s PNR & PNRU series liquid level control
•PC-xxx-LLC-GM is compatible with Gems’ series 16M general purpose control
•Must use model OT08PC or P1011-6 for UL rating. Manufacturer's recommended screw terminal torque for the OT series octal sockets is 12 in-lbs.
