VE4003S2B6 M-Series Analog Input Card | Emerson

Configured for high-density analog signal acquisition in DeltaV automation networks, the Emerson VE4003S2B6 (VE4003S2B6 Analog Input Card) provides direct physical/electrical execution of 16-channel 4-20 mA HART signal monitoring.

Hardware Specifications

Process Control: 4-20 mA HART Loop Protocol

The VE4003S2B6 facilitates the integration of smart instrumentation by supporting the 4-20 mA HART loop protocol. This module enables the simultaneous acquisition of the analog process variable and the overlay of digital HART communication for device diagnostics and remote configuration. The internal circuitry provides individual signal conditioning for each of the 16 channels, ensuring consistent data resolution. The architecture supports standard HART FSK signaling, maintaining signal fidelity across long-distance field runs while adhering to the standard impedance characteristics required for HART communication compliance.

Frequently Asked Questions (FAQ)

Q: Does the VE4003S2B6 support hot-swapping?

A: The VE4003S2B6 is designed for use on M-Series carriers that support hot-swapping. Ensure the channel is offlined in the DeltaV configuration to prevent the transmission of incorrect process variable values to the controller logic during module extraction or insertion.

Q: Are the 16 channels electrically isolated from each other?

A: The VE4003S2B6 maintains standard channel-to-channel isolation requirements for DeltaV M-series analog input modules. This prevents common-mode noise propagation between loops, though external grounding practices must be maintained to ensure the efficacy of the isolation barrier.

Field Installation Guidelines

• Mounting: Seat the module into the designated slot on the M-series carrier. Verify that the backplane connector is fully engaged and the locking mechanism is secured to prevent communication interruptions caused by mechanical vibration.

• Wiring: Utilize shielded twisted pair cabling to minimize electromagnetic interference on the 4-20 mA HART loops. Terminate cable shields at the carrier's grounding bus to establish a low-impedance path to cabinet earth.

• Termination: Ensure that the input impedance of the connected field loops complies with HART communication requirements. High loop resistance can attenuate the digital FSK signal overlay, leading to communication dropouts.

• Verification: Perform a loop integrity check using the DeltaV workstation diagnostics to verify correct signal scaling and HART signal presence upon system startup.
