Emerson VE4005S2B4 DeltaV M‑Series 8‑Channel 4-Wire Analog Input Card

Product Description

The Emerson VE4005S2B4 is an M‑Series analog input card for the DeltaV distributed control system, designed for 8‑channel 4‑wire 4‑20mA transmitters. It acquires high‑precision process signals from external powered instruments such as pressure, temperature and flow transmitters. It features channel isolation, built‑in diagnostics and hot‑swap capability, widely stocked as spare parts for petrochemical, power and refining plant DCS maintenance and retrofit projects.

Product Functions

• 8-channel 4-wire 4-20mA analog input for externally powered field transmitters
• High-accuracy signal conversion and transmission to DeltaV controllers and operator stations
• Independent channel isolation and overvoltage protection against field electrical noise
• Built-in self-diagnosis to detect open circuit, short circuit and out-of-range signals
• Hot-swap support, card replacement without stopping the DeltaV control node
• Onboard status indicators for quick visual inspection of channel and card health

Application Scenarios

• Petrochemical, refinery and natural gas DeltaV DCS process control systems
