Emerson VE3007 KJ2005X1-BA1 Analog Input Module

VE3007 with part codes KJ2005X1-BA1 and 12P4375X012 is an 8-channel analog input module for Emerson DeltaV DCS system. It receives 4-20mA two-wire transmitter signals and supports HART communication, converting analog field signals into digital data to transmit to DeltaV controllers via redundant bus. Each channel features reinforced isolation to block ground loop interference in chemical, power and oil & gas industrial sites.

This standard DCS I/O board is a core maintenance spare for legacy DeltaV distributed control systems. It adopts conformal coated PCB to resist damp and corrosive gas, supports hot-swap replacement without rack power-off, and front panel LED lights quickly identify open circuit, over-range and communication faults for on-site maintenance.

Core Functions

• Collect real-time 4-20mA signals from pressure, temperature, flow and liquid level transmitters for DeltaV process monitoring and closed-loop control.
• HART pass-through allows operators to read transmitter self-check data, adjust measurement ranges and perform online calibration without extra hardware.
• Independent channel isolation prevents single-channel short circuit or surge damage from spreading to other measurement loops and main controllers.
• Built-in multi-stage filtering suppresses electromagnetic interference from inverters and large motors to ensure stable analog measurement data.
• Hot-swappable modular design enables independent module replacement without shutting down the whole DCS rack, reducing continuous production downtime risk.
• Dual redundant I/O bus automatically switches communication links when bus failure occurs to guarantee uninterrupted process data transmission.
