Use the XH-M203 to refill an overhead water tank automatically. When the water falls to the lower float switch, the relay starts the filling cycle. The pump keeps running until the water reaches the upper switch, then stays off until the level falls again.
Where to use it
Control a filling pump for a rooftop storage tank, irrigation reservoir or hydroponic tank. Set the start and stop levels by placing compatible float switches at the desired heights.
Specifications
- Controller supply: 12V AC or DC
- Level inputs: two 2-pin XH2.54 sockets for upper and lower float switches
- Relay contact rating: up to 10A at 250V AC or 30V DC for resistive loads
- Onboard status LEDs and four mounting holes
- Approximate size: 60 × 40 × 18 mm
For a motor pump, check its starting current and use a suitably rated motor contactor when required. The board itself takes a 12V supply.
