Water-level relay for AC/DC 24-240 V systems

The Vszerda GRL8 is a water-level control relay supplied with a stainless-steel sensor probe. It operates on supply voltages from 24 V to 240 V AC or DC, making it suitable for tanks, sumps or reservoirs in domestic, agricultural or light-industrial settings. The single-channel relay switches a connected pump or valve when the probe detects the liquid level. Buyers who need multi-point level sensing or a built-in display should look elsewhere.

Simple two-wire probe installation

Wiring requires only the supply input, the relay output and the two sensor leads; no separate controller or programming is involved. The stainless probe resists corrosion in clean water, but debris or heavy scale can bridge the electrodes and cause false triggering. Ensure the probe is mounted vertically with the tip at the desired switch point and that cable glands are sealed to prevent moisture ingress. Incorrect polarity on the DC supply will prevent operation.

Questions about this item

How do I verify the relay switches correctly after wiring the stainless sensor?

Apply power within the AC/DC 24 V to 240 V range and watch the relay LED; it should change state when the sensor contacts water, confirming the level control is working.

What comes in the box and do I need any extra parts?

The package includes the GRL8-02 relay unit and one stainless sensor; no additional components are required for basic operation.
