## Summary description

Liquid level control relay FF PZ-829 RC is a 2-pole device rated 16A designed to operate with three probes. It accepts probe input resistance in the range 1–100 kΩ and monitors liquid levels to switch pumps or alarms. Suitable for tank level control, sump pumps, and simple automation where probe-based level detection and on/off switching are required.

## Long description

FF PZ-829 RC is a liquid level control relay configured as a 2-pole switching device with a rated current of 16 A, designed to work with three external probes. The unit accepts probe input resistance between 1 and 100 kΩ and monitors liquid levels to provide on/off control for pumps, valves or alarm circuits. It is intended for basic tank level control, sump pump protection and simple automation schemes where mechanical floats are not used and probe-based detection is preferred.
Advantages
The relay offers two-pole switching capable of handling up to 16 A, enabling direct control of many small pumps and actuators. Compatibility with a wide probe resistance range (1–100 kΩ) allows use with different probe materials and probe lengths. The three-probe arrangement supports simple empty/full control logic or a high/low alarm combination without additional external logic modules. The compact design and straightforward wiring simplify installation and maintenance.
Suitable for
Control of domestic and small commercial water tanks
Sump pump on/off control to prevent flooding
High/low level alarm systems in reservoirs and cisterns
Basic automation for irrigation, cooling circuits, or simple process vessels
Key specifications
Switching poles: 2-pole relay
Rated switching current: 16 A
Probe input resistance range: 1–100 kΩ
Probe configuration: designed for three probes (common, high, low)
Intended function: liquid level monitoring and on/off switching
How to use
Install the relay in a dry, ventilated enclosure or on a DIN rail according to local electrical regulations. Connect the three probes to the designated terminals (common, high, low) and ensure secure connections. Wire the load (pump, valve or alarm) to the relay output contacts suitable for the 16 A rating, and provide an appropriate supply voltage as specified in the product documentation. Calibrate probe positions in the tank so that the high and low probes correspond to the desired switching thresholds. Test the system without load first to verify correct probe detection and switching behavior.
Usage recommendations
Use corrosion-resistant probes appropriate for the liquid type and ensure probe wiring is routed to avoid electrical noise. Do not exceed the relay's 16 A switching rating; fit an external contactor for larger loads. Periodically inspect probe terminals and relay contacts for corrosion or loose connections and replace probes if insulation degrades.
