AC 0–20A Current Sensor Module — Switch Output, DC 24V, FullRange Linear Detection (0 to 20A) Key benefits Reliable AC current detection across the full 0–20A range so you can monitor and respond to load changes without gaps in sensitivity. Switch output simplifies integration with control systems, relays, PLCs or alarm circuits — no complex signal conditioning required. Designed for systems powered from DC 24V, making it compatible with standard industrial control supplies and many automation environments. Helps protect equipment and reduce downtime by enabling fast, repeatable overcurrent detection and control actions. What this module does (functionality) Measures AC current from 0 to 20 amperes and provides a switchstyle output when configured threshold(s) are reached. Uses fullrange linear detection across 0–20A so the sensor response remains consistent across the entire measurement span. Operates from a DC 24V supply and provides a discrete switch output that can directly interface to controllers or alarm inputs expecting a switching signal. Compatibility and interfaces Compatible with AC circuits where current up to 20A must be monitored. Works with control and automation systems that provide or accept DC 24V power and switch inputs (PLCs, relay modules, alarm systems, motor starters). Switch output removes the need for ADC channels or analog input scaling in many applications — use it for thresholdbased control and protection. Key attributes Measurement range: AC 0 to 20 A Output type: switch output (digital switching signal) Supply voltage: DC 24 V Detection characteristic: fullrange linear detection across 0–20A Intended use: inline/currentsensing module for monitoring and protection Performance and reliability Fullrange linear detection provides consistent behavior from the lowest to the point of the specified range (0–20A), enabling reliable threshold triggering and simpler system tuning. Switch output minimizes processing requirements on the host controller and reduces integration complexity in thresholdbased applications. Typical applications (use cases) Overcurrent detection and automatic shutdown: monitor motor or pump loads and trigger a relay or alarm when current exceeds a safe threshold to prevent damage. Panel and machinery protection: integrate into industrial control panels to provide a discrete trip signal to PLC inputs or contactors when an overcurrent condition occurs. Load monitoring and control: use the switch output to implement simple energymanagement rules (e.g., disable noncritical loads when measured current exceeds a preset value). Installation and integration notes Requires a DC 24V supply; ensure your control system provides the correct voltage before installation. Designed for threshold/switchbased control. If you need continuous analog measurement or a voltage/current proportional output, verify the module's output type meets your system requirements. Consult the product listing or datasheet for wiring diagrams, recommended connection practices, and any configuration or calibration steps.
