Product Performance

Supports dual-range analog input, directly compatible with voltage-type and current-type sensors, meeting diverse signal acquisition needs without additional conversion components.

±0.1% high-precision acquisition feature, combined with built-in filter and denoising circuit, can effectively filter out on-site interference signals, ensuring the accuracy and stability of collected data.

Input-output electrical isolation structure, combined with industrial-grade EMC anti-interference design, can isolate strong electrical interference and high-frequency signal interference, ensuring reliable signal transmission.

Industrial-grade wide temperature resistance design can operate stably under extreme high and low temperature working conditions, adapting to the deployment of industrial sites in various environments such as high-temperature workshops and outdoor pump stations.

Deeply compatible with PLC/DCS systems and series modules, supporting modular expansion, it can be flexibly combined according to acquisition needs, adapting to automation projects of different scales.

Rail-mounted installation combined with hot-swap function facilitates installation and disassembly, and can be maintained and replaced without stopping the system, greatly shortening operation and maintenance downtime.

Stable 24VDC power supply design adapts to voltage fluctuations in industrial sites, with reasonable power consumption control, balancing acquisition performance and energy efficiency optimization, and extending equipment service life.

Adopting high-durability industrial materials, it has corrosion resistance and wear resistance, can resist dust and oil pollution in industrial sites, and has excellent reliability.
