4D33804G03 Gen3 High-Isolation Jumper Configurable Universal Multi-Signal Isolated Terminal Daughter Card for Common Q Class 1E Nuclear Safety DCS

Full NRC Class 1E nuclear safety certified, the 4D33804G03 is the third-generation reinforced universal multi-signal terminal daughter card upgraded on standard G01 model for Emerson Westinghouse Common Q safety I&C platform. Each channel supports jumper switching of three signal types: passive dry contact discrete input, 4–20mA/0–10V analog input, 3-wire PT100 RTD temperature input, which optimizes cabinet slot utilization and reduces on-site wiring workload for mixed measurement points. Every channel is equipped with 2000V reinforced galvanic isolation and 50dB high-order multi-stage LC EMI filter banks, which fully suppress power frequency coupled noise, wide-amplitude ground loop potential drift and high-energy lightning surge transients. The PCB adopts multi-layer thick copper zero-halogen V-0 flame-retardant high-Tg substrate, matched with triple-thick hard gold-plated backplane connectors and heavy-duty corrosion-resistant nickel alloy terminal blocks. This card integrates full-channel microsecond-level intelligent fault diagnosis, fault transient waveform capture, non-volatile historical fault logging and multi-layer comprehensive circuit protection. It supports hot-swap online replacement without disturbing other safety measurement loops, delivering ultra-stable long-term signal acquisition performance under extreme composite environments of wide temperature fluctuation, high humidity, heavy dust and continuous strong mechanical vibration.
