Typical use cases include pump control, high/low level alarms and automatic filling or emptying systems in industrial and residential installations.

## Long description

FF PZ-828B is a liquid level control relay for monitoring and managing fluid levels in tanks, reservoirs and similar containers. It is designed to work with a 230 V AC supply and provides a switching capacity suitable for controlling pumps and alarm circuits. The relay accepts probe input resistances between 1 and 100 kΩ, making it compatible with common conductive level probes used in industrial and residential installations.
Advantages
The unit offers reliable on/off control with a rated switching capacity of 16 A, enabling direct control of many standard pumps and valves. Its wide accepted probe resistance range (1–100 kΩ) allows flexible integration with various probe types and installation conditions. The device is compact and intended for mounting in control panels or near the monitored vessel, providing a straightforward electrical interface for level control and alarms.
Suitable for
Pump start/stop control in supply and drainage systems
High-level and low-level alarm circuits
Automatic filling and emptying systems
Small industrial tanks and domestic water tanks
Key specifications
Operating voltage: 230 V AC
Switching capacity: 16 A
Probe input resistance range: 1–100 kΩ
Control function: liquid level monitoring and relay switching
Intended installation: panel or equipment mounting near tank
How to use
Install the relay according to local electrical codes and the manufacturer's mounting guidance, ensuring the unit is connected to a 230 V AC supply. Connect the conductive level probes to the probe input terminals, keeping wiring and probe placement appropriate for the liquid type and tank geometry. Wire the relay output to the pump, valve, or alarm circuit, observing the 16 A switching limit and using a contactor if switching higher loads. Verify correct operation by testing high and low level conditions and adjust probe positions as required for the desired activation points.
Usage recommendations
Use probes and wiring rated for the liquid and environment (corrosion, conductivity, temperature). For loads exceeding 16 A or inductive motors, add an intermediate contactor to protect the relay contacts. Periodically inspect probe connections and relay terminals for corrosion or loose wiring to maintain reliable operation.
