Submersible Pump Control Relays
A submersible pump control relay is a protection and control device that monitors the current and mains voltage of a submersible pump motor and stops the motor on dry-run, overload and voltage faults; it is chosen according to the phase type, motor current, protection functions and case size. It is used in borehole and tank filling systems to run the pump according to the water level in the well and tank and to protect the motor from faults. The category includes Tense MDK series single-phase and TDK series three-phase models; there are current ranges such as 1-30 A, 2-40 A, 1-120 A and 1-300 A, DIN rail type, and panel-type cases of 72 × 72, 96 × 96 and 144 × 144 mm. Some models include a built-in contactor, star-delta output or electrodeless well monitoring. Determine the current range according to the motor's nameplate current; whether the current measurement is internal or made with an external current transformer varies by model. A submersible pump control relay is not merely a liquid level relay that gives a contact based only on level information; in addition to level monitoring, it protects the motor against current and voltage faults.

How to choose Submersible Pump Control Relays
A submersible pump control relay is a protection and control device that monitors the current and mains voltage of a submersible pump motor and stops the motor on dry-run, overload and voltage faults; it is chosen according to the phase type, motor current, protection functions and case size. It is used in borehole and tank filling systems to run the pump according to the water level in the well and tank and to protect the motor from faults.
- Separate sensing, motion control, logic processing and operator interface requirements.
- Select signal type, supply voltage, communication protocol and I/O count for the machine network.
- Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
