Product Performance

The kit adopts independent channel isolation design, 8 inputs support mixed access of dry contact and active signals, and signal types can be configured via software without hardware jumpers, adapting to diverse on-site equipment. 4 relay outputs adopt forced-guided contact structure, ensuring no misoperation when single contact fails, meeting SIL 2 safety level requirements.

Integrated with programmable logic control function, it supports basic logic such as AND/OR/NOT and complex instructions such as delay and edge detection, with logic operation cycle ≤1ms, enabling rapid interlock response of fault signals. Data interaction delay with 3500 system monitoring module is ≤3ms, supporting input signal debounce setting (1ms-10s adjustable) to effectively filter on-site interference signals.

Built-in comprehensive self-diagnosis functions, it can real-time monitor input open circuit, output short circuit, relay sticking and module power abnormalities, with diagnostic coverage ≥99%, and fault status fed back through dual channels of LED indicators and system bus. Wide temperature adaptability and high isolation level design ensure stable operation in industrial strong electromagnetic environments, with overall mean time between failures (MTBF) ≥300,000 hours.
