4D33888G01 Standard High-Density 16-Channel Jumper Configurable Universal Mixed-Signal Isolated Terminal Daughter Card for Common Q Class 1E Nuclear Safety DCS

NRC Class 1E nuclear safety certified, the 4D33888G01 is a high-density compact universal multi-signal acquisition terminal daughter card developed exclusively for Emerson Westinghouse Common Q nuclear safety I&C platform. Each channel supports on-board jumper switching of three core signal types: passive dry contact discrete input (DI), standard 4–20mA / 0–10V analog input (AI), and 3-wire PT100 RTD temperature input (RTD). It realizes unified centralized collection of safety interlock switch feedback, process measurement analog signals and equipment temperature monitoring signals, drastically reducing cabinet slot occupation and on-site wiring construction workload for mixed multi-type field measuring points in nuclear auxiliary safety systems.
