Emerson VE4036P2 DeltaV Serial Interface Card

The Emerson VE4036P2 serves as the primary VE4036P2 Redundant M-Series Serial Interface Card utilized to execute serial data exchange and protocol translation across DeltaV network platforms.

Hardware Specifications

DCS Network Execution & Protocol Management

• Integrated Channel-to-Channel Isolation: The serial interface card features physical galvanic isolation between channels, preventing ground loops and protecting the internal processor bus from high-voltage field-side line transients.
• 4-20 mA HART Loop Protocol Coexistence: Onboard filter networks suppress electrical noise and electromagnetic interference, preventing communication harmonics from corrupting adjacent analog 4-20 mA HART loop protocol lines.
• Deterministic Serial Communication: Supports standard industrial serial protocols (such as Modbus RTU/ASCII) to bridge field devices directly into the DeltaV control database.

Frequently Asked Questions

Q: How does the redundancy mechanism switch over on the VE4036P2?

A: The card operates in an active/standby redundant pair configuration on a redundant carrier. In the event of an active card hardware failure, control and communication states transfer to the standby unit within milliseconds to avoid data loss.

Q: Can this serial card be hot-swapped while communication is online?

A: Yes. Individual VE4036P2 modules can be hot-swapped on a redundant carrier without powering down the carrier. The standby module will automatically assume active communication duties.

Field Installation Guidelines

• Carrier Mounting and Alignment: Align the module rear connectors with the mating redundant carrier slots. Slide the card in smoothly and tighten the captive fastening screws to secure the physical connection.
• Shield Grounding Method: Terminate serial cable shields (RS485/RS232) strictly at the designated single-point cabinet ground bar. Do not ground the shield at both ends to avoid ground loop current interference.
• Signal Line Isolation: Route serial communication lines through dedicated, shielded conduits, maintaining a minimum physical separation of 300 mm from high-voltage AC cables.
• Terminating Resistors: Install appropriate terminating resistors (e.g., 120 Ohm for RS485 loops) at the physical end-of-line nodes to stabilize signal integrity and prevent data reflections.
