Emerson VE4003S2B6 Analog Input Module

Hardware Specifications

Emerson 4-20 mA Process Signal Interface

The VE4003S2B6 integrates a 16-channel analog input interface for two-wire 4-20 mA field devices. It receives current loop signals from transmitters and transfers measured values through the DeltaV I/O architecture.

Furthermore, the module supports Emerson process control signal handling methods, including current loop monitoring and channel-to-channel signal separation. The design allows connection of multiple field instruments while maintaining individual input processing paths.

The module operates with DeltaV Series 2 I/O hardware and uses the LocalBus communication structure for controller-side data exchange. Additionally, the field power distribution supports connected two-wire transmitter circuits through the bussed field power supply.

Frequently Asked Questions

Q: What input signal type does the VE4003S2B6 support?
A: The VE4003S2B6 supports 4-20 mA analog input signals from two-wire field transmitters.

Q: How many input channels are available on this module?
A: The VE4003S2B6 provides 16 analog input channels for process measurement signals.

Q: What are the power requirements of the module?
A: The module requires 12 VDC at 150 mA for LocalBus power and supports 24 VDC at 600 mA bussed field power.

Field Installation Guidelines

Install the VE4003S2B6 in the designated Emerson DeltaV M-series rack position according to system hardware documentation.

Use shielded signal cables for 4-20 mA field wiring where required by the site electrical design. Connect cable shields according to the plant grounding standard to reduce electrical interference.

Separate analog signal wiring from high-current power cables and switching circuits. Verify field transmitter polarity, loop continuity, and terminal assignments before applying field power.

Confirm that the rack backplane connection is fully seated before system startup. Check LocalBus communication status and field circuit conditions through the DeltaV diagnostic interface after installation.
