## Summary description

ORNO OR-PZ-466 is a single-module water level control relay designed to monitor and manage liquid levels in two separate tanks. Compatible with a wide supply range of 24–240 V AC/DC, it provides relay switching for automated filling or draining operations. Suitable for domestic and light industrial applications where reliable level detection and simple control of pumps or valves are required.

## Long description

ORNO OR-PZ-466 is a single-module water level control relay engineered to monitor and control liquid levels in two independent tanks. Designed for a wide supply voltage range from 24 to 240 V AC/DC, the module provides relay outputs suitable for driving pumps, solenoid valves or other control devices to automate filling and draining cycles. The compact, DIN-rail compatible form factor and straightforward wiring make it suitable for domestic installations and light industrial setups where reliable level management is needed.
Advantages
The device supports both low and high supply voltages within the 24–240 V AC/DC range, enabling flexible integration into existing electrical systems. Its single-module design conserves panel space while offering separate level monitoring for two tanks. Relay switching provides galvanic isolation between control circuitry and driven equipment, improving safety and compatibility with common pump and valve controls. The unit’s simple configuration and clear terminal layout facilitate fast installation and maintenance.
Suitable for
Automation of filling and draining of domestic water tanks
Control of small booster or sump pumps in residential and light commercial systems
Level monitoring in rainwater harvesting and irrigation setups
Simple level control tasks in workshops, greenhouses or utility rooms
Key specifications
Supply voltage range: 24–240 V AC/DC
Single-module (DIN-rail compatible) enclosure
Two-tank level detection capability (separate inputs for each tank)
Relay output(s) for switching pumps or valves
Designed for use with conductive level probes or sensor inputs
How to use
Mount the module on a compatible DIN rail and connect the supply voltage within the specified 24–240 V AC/DC range. Wire separate level probes or sensor leads for each tank to the designated input terminals, and connect the relay output(s) to the pump or valve control circuits following local electrical codes. Configure the control logic according to the installation needs—typical setups include pump start on low-level and stop on high-level or vice versa for draining applications. Verify correct operation by testing level sensors and observing relay switching before leaving the system in automatic mode.
Usage recommendations
Use compatible conductive probes or sensors and ensure proper sealing and cable routing to avoid moisture ingress. Where required, include appropriate protective devices such as fuses or circuit breakers and ensure pump motors are protected against dry-run conditions. Perform periodic checks of sensors, electrical connections and relay operation to maintain reliable level control.
