Our 2 Input 2 Output (2DIDO) wireless RTU is an intelligent relay device designed for automatic pump control based on liquid level status. It features two digital inputs (for level sensors) and two relay outputs (for pump control), providing a reliable and cost-effective solution for water tanks, sump pumps, industrial liquid management, and remote monitoring systems.
Key Features
Dual Input Monitoring
– Supports two level sensors (e.g., float switches, ultrasonic, or pressure sensors) for high/low liquid level detection.
Dual Relay Outputs
– Two relays to control pumps, valves, or alarms independently.
Flexible Logic Control
– Configurable Normally Open (NO)/Normally Closed (NC) operation for different automation needs.
Wide Voltage Input (12-24V DC)
– Compatible with most industrial and solar-powered systems.
LED Status Indicators
– Visual feedback for power, input signals, and relay activation.
Compact & DIN-Rail Mountable
– Easy installation in control panels or junction boxes.
Typical Applications
Water Tank Automation – Control fill/drain pumps based on high/low levels.
Sump Pump Systems – Prevent overflow or dry running.
Industrial Liquid Management – Chemical dosing, irrigation, and wastewater control.
Remote Monitoring Integration – Works with PLCs, SCADA, or IoT controllers.
Why Choose Our Controller?
Reliable & Durable – Industrial-grade components for long-term operation.
Easy to Install – No programming required, plug-and-play setup.
Cost-Effective – Eliminates the need for complex PLC systems in basic applications.
