Product Performance
High reliability: designed for critical rotating machinery, compliant with API 670 standard, mechanical relays can operate stably for a long time, ensuring reliable operation of industrial systems.
Flexible configuration: With 60 inputs, 30 logical expressions, and 16 relay outputs, various complex control logics can be implemented through simple software configuration to meet the needs of different industrial scenarios.
Hot plugging function: Supports hot plugging, allowing modules to be directly plugged in and out for maintenance or replacement during system operation without shutting down, reducing system downtime and improving production efficiency.
Isolation protection: There is a 500V rms isolation between input/output, which can effectively prevent electrical interference, protect the system from voltage spikes and electromagnetic interference, and ensure the stability and accuracy of signal transmission.
Space saving: Adopting a 3U size, 2-slot plug-in module design, it reduces the cabinet space requirement by half compared to traditional 6U size cards, which is beneficial for optimizing the layout of control cabinets and improving space utilization.
