4D33804G04 Gen4 Ultra-High Isolation Flagship 12-Channel Jumper Configurable Universal Multi-Signal Isolated Terminal Daughter Card for Common Q Class 1E Nuclear Safety DCS

Fully certified to NRC Class 1E nuclear safety standards, the 4D33804G04 is the fourth-generation top-tier fully optimized universal multi-signal terminal daughter card, iteratively upgraded based on G01/G02/G03 versions for Emerson Westinghouse Common Q safety I&C platform. Each channel supports jumper switching for three core signal types: passive dry contact discrete input, 4–20mA / 0–10V analog input, and 3-wire PT100 RTD temperature input. It realizes unified acquisition of interlock switch signals, process measurement analog signals and equipment temperature signals, drastically reducing cabinet slot occupation and field wiring construction volume for mixed measurement points in nuclear safety systems.

Description

4D33804G04 Gen4 Ultra-High Isolation Flagship 12-Channel Jumper Configurable Universal Multi-Signal Isolated Terminal Daughter Card for Common Q Class 1E Nuclear Safety DCS

Product Brief

Each channel is built with 2200V ultra-high reinforced galvanic isolation and 55dB fifth-order multi-stage EMI filter arrays, thoroughly eliminating power frequency coupled interference, large-amplitude ground loop potential drift and ultra-high-energy lightning surge transient noise. The PCB adopts multi-layer ultra-thick copper zero-halogen V-0 high-Tg flame-retardant substrate, equipped with quadruple thick hard gold-plated backplane edge connectors and heavy-duty anti-corrosion nickel alloy large-caliber terminal blocks. This daughter card integrates full-channel microsecond-grade intelligent fault diagnosis, full capture of fault transient waveforms, large-capacity non-volatile historical fault storage, multi-layer full-range circuit protection and uninterrupted hot-swap online maintenance; module replacement does not affect the normal operation of any adjacent safety measurement loops, providing ultra-long-term stable high-precision signal acquisition capability under extreme composite harsh environments with wide temperature swings, high humidity, heavy dust accumulation and sustained intense mechanical vibration.
