Emerson VE4003S2B9 Simplex Analog Input Card

Hardware Specifications

4-20 mA HART Loop Protocol and Channel Isolation

The VE4003S2B9 integrates analog measurement acquisition with HART communication functions for DeltaV process control applications. Therefore, each input channel receives a continuous 4-20 mA field signal while supporting digital HART data transmission over the same current loop.

The module design follows Emerson DeltaV I/O architecture requirements, allowing process instruments to exchange measurement values and configuration information through HART-enabled field devices. Additionally, proper field wiring practices maintain signal integrity and reduce electromagnetic interference during operation.

Frequently Asked Questions

Q: Does the VE4003S2B9 support HART communication on analog input channels?
A: Yes. The VE4003S2B9 supports HART communication over 4-20 mA analog input loops for compatible field instruments.

Q: How many analog input channels are available on the VE4003S2B9?
A: The module provides 16 analog input channels for process signal acquisition.

Q: What termination method is required for the VE4003S2B9?
A: The module uses a 2-wire standard termination block interface for field signal connection.

Field Installation Guidelines

Install the VE4003S2B9 module according to DeltaV hardware installation procedures and approved cabinet layouts.

Use shielded instrumentation cable for analog signal wiring where required by the installation environment. Connect cable shields according to site grounding standards to minimize electrical noise.

Separate analog signal cables from high-voltage power cables and switching circuits. Verify terminal assignments before applying field power to prevent incorrect loop connections.

Confirm that connected transmitters match the 4-20 mA input requirements and that HART communication wiring maintains correct polarity and loop continuity.
