| Datasheet | Download Datasheet |
The Macromatic LCP2J250 is a liquid level control relay rated 10 A at 240 V AC, 7 A at 28 V DC, driven by a 120V AC input.
It controls the level of a conductive liquid, pumping down to drain the tank.
It switches between a high and a low probe, so the gap between them sets how far the level travels before the pump runs again.
The setpoint covers 1K to 250K ohms between probe and common, so it is the conductivity of the liquid that decides the part.
The probe is pulsed with 5 V DC rather than held at a steady potential, which is what stops it electroplating away in service.
Its pinout is wired to cross to GEMS (Warrick) products.
It has Socketable mounting and Plug In terminals.
