Structural and Installation Advantages

Open-close Integrated Structure

Adopt open-close integrated design, no need to disconnect the measured cable or remove the original terminal during installation, realizing live installation and maintenance, greatly shortening construction time and reducing power outage loss.

High Integration and Strong Stability

Integrate sampling, amplification, conversion and isolation in one, with compact structure and small space occupation. The fully enclosed epoxy casting and flame retardant shell provide excellent insulation, moisture resistance and anti-vibration performance, adapting to harsh industrial environments.

Wide Adaptation and High Compatibility

Support a wide range of current input and multiple standard signal output, compatible with PLC, DCS, monitoring instruments and cloud platforms, meeting the access requirements of different systems.

Simple and Firm Installation

Equipped with special buckle or screw fixing structure, easy to install in distribution cabinet, cable trench and equipment side, stable and not easy to loose, suitable for various standard electrical installation scenarios.

Installation & Maintenance

1. Open the transmitter shell, pass the measured cable through the core hole and close the shell firmly.
2. Fix the transmitter with matching screws or buckles to ensure stable placement.
3. Connect the power supply and output signal line to the corresponding terminal, and connect the shield wire reliably.
4. Check the wiring and fastening, then power on for operation.

Daily maintenance is simple, only need to check the fastening state and terminal connection regularly, no complicated calibration and maintenance operations are required.
