12Vdc Fluid Level Controller Relay Module

12Vdc Fluid Level Controller Relay Module for controlling liquid level in tanks, wells, reservoirs etc. Adjustable height Minimum and Maximum sensors supplied enable automatic control of fluid level in a vessel using the onboard relay to operate a pump (not included) of up to 240Vac or 28Vdc, 5 Amps. Circuit uses the popular 4093 IC.

The module provides two modes of operation:

1. DRAIN mode allows you to automatically pump fluid out when the level rises above the Maximum level. The module turns the pump off once the fluid falls to the Minimum level.
2. FILL mode allows you to automatically pump fluid in when the level falls below the Minimum level. The module turns the pump off once the fluid rises to the Maximum level.

Suitable for automated fluid distributors, drink dispensers, washing machines, irrigation systems, water and fuel tanks, burners, central heating, etc.

Minimum and maximum sensors included (with solder pads). Module features reverse polarity protection, relay active LED indicator and screw terminal blocks for connections. Output relay rated to switch 5 Amps @ 240Vac/28Vdc Max. Pump not included.
