AC 0-50A Current Sensor Transmitter Module | RS485 Output

AC 0–50A Current Detection Sensor & Transmitter Module with RS485 Output

Monitor AC current with precision using this compact, integrated mutual inductance current sensor and transmitter module. Designed for industrial control, energy management, and smart power distribution systems, this module delivers stable, reliable current readings across a full 0–50A range — all in one streamlined unit.

Key Features

• Wide Measurement Range: Accurately measures AC currents from 0 to 50A, making it versatile for a broad range of electrical systems and load types.
• True RMS Detection: Employs true effective value (True RMS) measurement technology for accurate readings even under non-sinusoidal, distorted, or fluctuating loads — ideal for variable frequency drives, switching power supplies, and complex electrical environments.
• Integrated Sensor + Transmitter Design: The mutual inductance sensor and signal conditioning transmitter are built into a single compact module, reducing wiring complexity, simplifying installation, and improving overall system performance versus traditional discrete setups.
• RS485 (Modbus) Output: Outputs measurement data directly to RS485 acquisition modules, enabling seamless integration into industrial automation, SCADA, and building energy management systems.
• High Precision: Delivers consistent, high-accuracy current readings suitable for demanding energy monitoring and control applications.
• Compact & Durable: Housed in a robust black plastic enclosure for reliable long-term use in industrial environments.

Frequently Asked Questions

Q: What AC current range does this sensor module measure?

A: This AC current detection sensor and transmitter module measures a full range of AC 0–50A, making it suitable for a wide variety of industrial, commercial, and energy management applications.

Q: What does True RMS detection mean and why does it matter?

A: True RMS (Root Mean Square) detection calculates the true effective value of an AC current signal, even when the waveform is non-sinusoidal or distorted. This ensures accurate measurements for variable frequency drives, switching power supplies, and other complex loads where standard average-responding sensors may give incorrect readings.

Q: How does this module connect to a monitoring system?

A: The module outputs data via an RS485 interface, which is compatible with standard RS485 acquisition modules and Modbus-based SCADA, industrial automation, and building energy management systems. This allows for easy integration into existing monitoring networks.

Q: Is this module easy to install?

A: Yes. The integrated design combines the mutual inductance sensor and signal conditioning transmitter into a single compact unit, greatly reducing wiring complexity and simplifying installation compared with traditional discrete sensor-plus-transmitter setups.
