Description
M131 Controller – intelligent controller for three-phase pumps
The IBO M131 controller is a professional electronic controller designed to control the operation of a single three-phase pump and provide comprehensive protection. It automates pump activation and deactivation depending on the water level or pressure, while continuously monitoring the power supply and motor operating parameters. Its key feature is effective dry-running protection, which works even without installing probes in the well, keeping installation simple and the pump permanently protected.
Who is it for?
- Installers and electricians – the M131 controller organizes the connection of a three-phase pump and simplifies the selection of protection devices through calibration tailored to the specific motor.
- Owners of homes and farms with a well water source – the controller automates water supply and protects the pump against costly failures.
- Farms and horticultural operations – the device monitors pump operation when irrigating fields, greenhouses, and gardens, as well as in rainwater management systems.
- Facilities with pumping stations and tanks – the controller activates and deactivates the pump according to the level or pressure, while an overflow probe warns of tank overfilling.
Applications
The M131 controller is suitable wherever a single three-phase pump needs to operate automatically and reliably. It works with submersible pumps for supplying water from wells, surface pumps in water supply systems, and drainage pumps in tanks, septic tanks, and drainage systems. It receives the activation and deactivation signal from level probes, floats, or a pressure switch working with a pressure tank, allowing it to be adapted to a wide variety of configurations.
The device controls the pump based on the water level in the tank from which it pumps, the level in the target tank, or the pressure in the system; in drainage mode, it also signals overflow. It is used in houses, apartments, holiday homes, farms, and industrial installations.
Features of the M131 controller
At the heart of the device is an electronic system with a clear LCD display that continuously shows the pump's operating status, parameters, and fault messages. The M131 uses dual dry-running protection – it analyzes the signal from probes or a float and the current consumption of the operating pump. Importantly, dry-running protection also works without installing probes in the well itself: after bridging the appropriate inputs, the controller detects dry running based on current consumption and stops the pump in time. After a fault occurs, the device automatically checks the conditions and resumes operation only after the irregularity has cleared.
The controller supports automatic and manual modes, while the built-in function switch allows the operating configuration to be matched to installations with a float, probes, or a pressure switch. As three-phase equipment, the M131 should be connected by a qualified installer in accordance with the instructions and applicable regulations. The most important parameters are listed below. Data distinguishing the two power variants are given after the slash.

Frequently asked questions (FAQ) – M131 controller
What is the M131 controller used for?
The M131 controller is an intelligent controller for automatically controlling the operation of a single three-phase pump and protecting it. It switches the pump on and off depending on the water level or pressure in the system and protects it against dry running and power supply irregularities.
Which pumps can be connected to the M131 controller?
The M131 works with three-phase submersible, surface, and drainage pumps supplied with 3~400 V. It is available in two supported pump power variants: 0.75–4 kW and 5.5–7.5 kW, allowing it to be matched to various installations.
Does the M131 protect the pump against dry running without installing probes in the well?
Yes. The M131 can detect dry running by analyzing the pump's current consumption, so effective protection also works when installing probes in the well is difficult or costly. When dry running is detected, the pump is stopped, and the controller attempts to restart it after the problem has cleared.
How does the M131 controller differ from the M121 model?
The M121 is designed for single-phase pumps supplied with 230 V, while the M131 supports three-phase 400 V pumps and additionally protects them against phase loss. You can find the full range of controllers in the controllers category.
Can the M131 controller be installed outdoors?
The M131 has an IP22 protection rating and is designed for indoor installation in a vertical position, in a dry, well-ventilated location. The device must be protected from water, including rainwater, so when the pump operates outdoors, the controller itself should be placed indoors or in a suitable protected enclosure.
Where can I buy the M131 controller?
As a manufacturer, we do not sell directly. The IBO M131 controller can be purchased from our trade partners, installation wholesalers, and authorized online distributors.
What is the warranty for the M131 controller?
IBO – 24-month (2-year) manufacturer's warranty.
