Product Performance
High reliability: With a sturdy extruded aluminum casing, it can adapt to harsh industrial environments. At the same time, it has redundant 2Mbps module fieldbus communication to ensure the stability and reliability of data transmission.
High precision measurement: The analog input accuracy can reach ± 0.03% of the full range, accurately measuring the analog signals of on-site equipment and providing precise data support for control systems.
Strong anti-interference ability: It has a high common mode rejection ratio (>100dB at 50 or 60Hz) and normal mode rejection ratio (>35dB at 50 or 60Hz), effectively suppressing electromagnetic interference on site and ensuring the quality of signal transmission.
Easy to maintain: It can be disassembled and replaced without cutting off the on-site wiring, power or communication cables, which facilitates on-site maintenance work and reduces downtime.
