DeltaV S-series SE4036P2 Serial Communication Card

Product Overview

The Emerson SE4036P2 functions as the high-speed communication gateway between the DeltaV S-series Distributed Control System (DCS) and external smart instrumentation. This module facilitates data exchange with third-party devices including PLCs, gas analyzers, and barcode scanners. By utilizing two independently configurable ports, the SE4036P2 enables the system to poll multiple devices using different protocols simultaneously. We supply this unit as 100% Brand New and Original, ensuring high-availability performance for critical industrial data loops.

Technical Specifications

Engineering Advantages

• Protocol Flexibility: Each port operates independently. This allows engineers to run a Modbus RTU master loop on Port 1 while Port 2 handles a dedicated serial link to an older PLC or specialty analyzer.

• Industrial Environmental Hardening: The SE4036P2 withstands extreme temperatures ranging from -40 C to +70 C. This eliminates the need for expensive cabinet cooling or heating systems in remote offshore or desert locations.

• High-Availability Redundancy: The module supports full hardware redundancy. If the primary module fails, the backup module assumes control of the serial communication without losing data packets or triggering system alarms.

• Simple Hot-Swap Integration: The plug-in design fits into standard 8-wide I/O carriers. Maintenance teams can replace modules without disturbing field wiring, significantly reducing Mean Time To Repair (MTTR).

FAQs

• Can the SE4036P2 handle both RS-232 and RS-485 at the same time?

  Yes. Because the two ports are independently configurable, you can set Port 1 to RS-232 for a local scanner and Port 2 to RS-485 for a multi-drop Modbus network of smart transmitters.

• Does this module require a separate power supply?

  No. The SE4036P2 draws its power directly from the DeltaV carrier backplane. This reduces wiring complexity and potential points of failure within the control cabinet.

• What is the maximum distance for RS-485 communication on this module?

  The SE4036P2 supports standard RS-485 distances up to 1200 meters (4000 feet) at lower baud rates, provided you use high-quality shielded twisted-pair cable and proper termination resistors.

• Is this module compatible with DeltaV M-series carriers?

  The SE4036P2 specifically targets the S-series hardware platform. Always verify your carrier type before installation to ensure mechanical and electrical compatibility.
