It adopts multi-layer high-temperature resistant FR-4 industrial PCB with full enclosed electromagnetic shielding layout, equipped with 1000V AC/DC galvanic isolation between external remote bus terminals and internal logic circuits, which effectively suppresses electromagnetic interference from high-voltage equipment, inverters and large rotating machinery in thermal power, petrochemical and metallurgical sites.Each board undergoes 72-hour high-low temperature cycle aging, full-load bus continuous communication testing, redundant channel switching simulation and complete hardware fault detection before delivery. It supports single-slot hot-swappable backplane plug-in without shutting down the whole DCS system, and integrates multi-stage surge suppression, overvoltage, overcurrent, reverse polarity and short-circuit protection circuits. Built-in independent LED diagnostic indicators for power supply, main bus link, remote channel status and hardware fault alarm, supporting rapid on-site troubleshooting, significantly improving expandability and continuous operation reliability of multi-station distributed DCS systems, and reducing unplanned production downtime and maintenance labor costs.
