Vszerda GRL8 Water Level Control Relay with Stainless Sensor AC/DC24V-240V

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.
