Product information

Description

The F&F PZ-831 RC is a professional liquid level control relay engineered to monitor and manage fluid levels in conductive liquid tanks, wells, or reservoirs. This device provides precise automation for pump systems or solenoid valves, ensuring that liquid levels remain within defined parameters to prevent overflow or pump damage due to dry running. Designed for seamless integration into electrical cabinets, it mounts directly onto a standard 35 mm DIN rail.

Advantages

The primary benefit of the PZ-831 RC is its ability to manage independent control levels, allowing for highly customizable automation logic. By utilizing conductive probes, the relay offers a reliable and maintenance-free solution for level detection. Its robust design ensures consistent performance in both domestic water supply systems and industrial liquid management applications. The DIN rail mounting capability simplifies installation and maintenance, making it an efficient choice for modern control panels.

Suitable for

Monitoring water levels in wells and boreholes
Managing liquid levels in industrial storage tanks
Automating pump systems for drainage or filling
Preventing dry running of pumps in irrigation systems
Controlling solenoid valves for fluid distribution

When it may not be suitable

This relay is specifically designed for conductive liquids such as water. It is not suitable for use with non-conductive fluids like oils, fuels, or aggressive chemicals that could damage the probes or fail to complete the electrical circuit.

Key specifications

Mounting type: 35 mm DIN rail
Control type: Independent level monitoring
Compatibility: Conductive liquids
Function: Pump or valve automation

How to use

Installation should be performed by a qualified electrician. Mount the relay onto the DIN rail and connect the power supply according to the wiring diagram. Install the conductive probes at the desired minimum and maximum liquid levels within the tank. Connect the pump or valve control circuit to the relay output terminals. Once powered, the device will automatically trigger the connected equipment based on the signals received from the probes.

What to consider before purchase

Ensure the liquid being monitored is conductive
Verify the voltage requirements of your pump or valve
Check the depth of the tank to ensure probe cable length is sufficient
Confirm the relay's output capacity matches your equipment load

Usage recommendations

Regularly inspect the conductive probes for scale buildup or debris to ensure accurate level detection and reliable operation of the relay.
