Description
The VE4003S2B3 is an analog input card from Emerson. The following is a detailed introduction:
I. Core Functions
Multi-channel Analog Input
The 8-channel design supports 4-20 mA current signal input, making it suitable for signal acquisition from industrial sensors, transmitters, and other devices.
HART protocol compatibility allows simultaneous transmission of analog signals and digital communications, facilitating device configuration, diagnosis, and maintenance.
The 4-wire terminal block provides more stable signal transmission and reduces line interference.
Signal Processing and Protection
Linearity Error Control: When connecting different sensors, the linearity error is ≤1.5% (PR6422) to ≤6.0% (PR6425), ensuring measurement accuracy.
Open/Short Circuit Protection: Automatically detects and isolates fault signals to prevent module damage.
Reverse Protection: Prevents circuit failures caused by wiring errors.
Output Characteristics
Output Voltage Range: DC voltage superimposed on an AC signal proportional to shaft vibration. Linear range: -4V to -20V (supply voltage: -24V), wide range: -1V to -22V.
Output Impedance: 100kΩ, suitable for various control system input requirements.

V. Purchasing Recommendations
Model Comparison
If you require a two-wire connection, choose the VE4003S2B1 or VE4003S2B2 (with fuse terminal blocks).
If you need 16-channel input, consider the VE4003S2B6 or VE4003S2B9.
If you require a redundant design, we recommend the VE4033S2B1 (4W) redundant analog input card.
