Out of Stock

The XH-M203 is a 12V DC/AC powered water level controller module designed for automatic pump control in tanks and reservoirs. It features a relay output rated for up to 10A (recommended 3A continuous) and uses high/low level sensor inputs for fully automatic operation, making it compatible with simple float switch or probe-based sensing systems.

Features

  • 12V DC/AC operating voltage for flexible power supply integration.
  • Relay output rated for 10A switching (3A continuous recommended for reliability).
  • Dual-level control via dedicated High and Low sensor input pins.
  • LED indicators for clear visual status of water level and relay state.
  • Compact PCB module design for easy enclosure and system integration.

Description

The XH-M203 Water Level Controller Module provides a robust solution for automating liquid level management in tanks, sumps, and reservoirs. It operates on a simple two-sensor principle, utilizing a max-limit (high) and min-limit (low) input to control an internal electromechanical relay. When the liquid level drops and triggers the low-level sensor, the relay energizes to power a pump or fill valve. Once the high-level sensor is triggered, the relay de-energizes, stopping the filling process. This creates a fully automatic hysteresis control loop.

Built around a reliable relay and supporting circuitry, the module is designed for durability in typical indoor and protected environments. The 12V AC/DC input voltage allows for integration with common power adapters or battery-backed systems, while the screw terminal or pin-header connections facilitate straightforward wiring with sensors and the controlled load.

Key Features

  • Dual-input level sensing for automatic pump or valve control.
  • Electromechanical relay output for direct switching of AC/DC loads.
  • Wide-range 12V AC/DC power input for versatile installation.
  • Clear LED indicators for power, high-level trigger, and low-level trigger status.
  • Compact and lightweight PCB design for space-constrained control panels.
  • High-value build with robust terminals for reliable long-term operation.

Applications

  • Automatic water tank level control for residential and agricultural water storage systems.
  • Sump pump automation in basements, crawl spaces, and industrial pits.
  • Liquid level management in aquariums, hydroponic systems, and aquaculture tanks.
  • Controlling coolant or lubricant levels in machinery and industrial equipment.
  • Automatic refill systems for chemical dosing tanks and reservoirs.

Frequently Asked Questions

What is the maximum load the XH-M203 relay can switch?

The relay contacts are rated for 10A at 250VAC/30VDC. However, for reliable long-term operation and to prevent contact welding, it is strongly recommended to derate the continuous current to 3A or less. For higher current loads, use this module to trigger an external, higher-rated contactor or solid-state relay.

What type of sensors are compatible with the High and Low level inputs?

The inputs are designed for simple dry-contact switches or probes. You can use float switches, conductive probes (with a suitable pull-up resistor), or any other sensor that provides a clean open/short circuit to ground. The module detects when the sensor circuit is closed (connected to ground).

Can I power this module with AC voltage?

Yes, the module accepts both 12V DC and 12V AC input. Ensure your power source (transformer or adapter) provides a stable 12V RMS AC output. The internal circuitry rectifies and regulates the AC input to DC for operation.

How does the automatic control logic work?

The logic is based on two independent sensors. When the Low sensor is triggered (circuit closed), the relay energizes (turns ON) to start filling. The relay remains ON until the High sensor is triggered, at which point it de-energizes (turns OFF) to stop filling. The system will not restart until the level falls again and the Low sensor is triggered once more.
