Product Performance

16 independent configurable output channels, supporting two output types: relay and PNP transistor, can flexibly adapt to on-site actuators of different load types with extremely strong versatility

Relay output supports AC and DC wide-voltage loads, and transistor output response speed is as fast as ≤100μs, which can meet the needs of conventional load control and high-speed response control respectively

High electrical isolation design between channels and between channels and backplane, combined with industrial-grade anti-electromagnetic interference circuit, can effectively resist on-site electromagnetic radiation and surge impact, ensuring the stability of output signals and the reliability of module operation

Each channel is equipped with targeted protection functions. Relay output adopts fuse protection, and transistor output adopts automatic current limiting protection, which can effectively avoid damage to the module caused by load faults and extend the service life of the module

Equipped with complete full-link fault diagnosis functions, it can real-time monitor channel working conditions, relay status, module operation and communication status, and fault information is uploaded to the controller in real time, facilitating operation and maintenance personnel to quickly locate and handle problems

Wide operating temperature range of 0℃ – 60℃, industrial-grade rugged packaging design, can long-term stable operation in complex industrial sites with high temperature, high humidity and multiple interferences, with strong environmental adaptability

Deeply compatible with the ABB AC 800M series control system, plug-and-play, supporting online configuration debugging and parameter configuration, simplifying system integration and later maintenance processes

High-reliability design, MTBF ≥3,000,000 hours, fully meeting the rigorous requirements of 24-hour uninterrupted operation in industrial sites
