Product Introduction
The VE4036P2 is a redundant serial interface card in the M‑series (Series 2) family, designed to bridge serial communication devices (e.g. Modbus, legacy serial equipment) with the DeltaV control system architecture. It contains a pair of serial cards plus a redundant terminal block, enabling continuous operation even if one path fails.
This module is tailored for industrial automation environments requiring high availability and guaranteed data links. Each card offers two serial ports supporting RS‑232 and RS‑422/485 protocols, and the system can automatically switchover in fault scenarios without interrupting the control operations. It’s plug‑and‑play in DeltaV systems: once configured via the control software, it integrates seamlessly into I/O carriers and works in conjunction with other modules.
Because it supports serial devices already in use in plants, it allows the existing instrumentation and controllers to be retained, bridging “brownfield” installations into modern automation systems without wholesale replacement.
Product Applications
-
Connecting Modbus RTU / ASCII devices (pressure transmitters, analyzers, PLCs) into DeltaV systems.
-
Interfacing with legacy serial equipment (e.g. older instrumentation, controllers) in modernization projects.
-
Redundant communication setups in safety‑critical applications (e.g. petrochemical, power plants).
-
Serial data acquisition and command/control in remote field devices.
-
Process control systems where continuous serial link uptime is required.
Product Advantages
-
Redundancy for Reliability
With 1:1 redundant cards, the module ensures continuous serial connectivity even if one card or port fails. -
Protocol Flexibility
Supports RS‑232 and RS‑422/485 (half or full duplex), enabling integration with a wide variety of field devices. -
Isolated Ports
Each serial port is electrically isolated from the system and from other ports, improving noise immunity and safety. -
Plug & Play Integration
DeltaV auto‑detects redundant I/O and treats the redundant pair as a single logical interface, simplifying configuration. -
Automatic Switchover
Upon detection of failure in the active card, it switches seamlessly to the standby card without requiring user intervention. -
Compact Design but Robust Specs
Despite its modest dimensions, it supports wide temperature ranges and shock/vibration resilience suited for industrial use. -
Preserves Existing Infrastructure
Allows reuse of serial devices already installed in plants, lowering upgrade costs and preserving investment. -
Diagnostics & Status Feedback
Offers realtime status indicators and diagnostic capabilities to detect communication faults, switchover events, or port issues.
