Foxboro P0924WV — I/A Series Control Processor Module for Foxboro DCS Systems

Meta Description

Foxboro P0924WV control processor module for Foxboro I/A Series DCS. Provides process control, data acquisition, Ethernet/ControlNet/RS-232 communications and optional controller redundancy. Verify nameplate, firmware and slot configuration before replacement.

Product Core Overview

The P0924WV is a Foxboro I/A Series control processor module used in Foxboro distributed control systems. It executes regulation, logic, timing and sequence control, acquires process variables, and communicates with operator stations, fieldbus modules and third-party systems.
It is typically installed in an I/A Series control processor slot and may be configured as a single controller or as part of a redundant pair. Depending on the system generation, it can connect to 200 Series FBM I/O modules through the Foxboro fieldbus architecture.
Note: Some third-party listings describe P0924WV as a pressure transmitter or alarm keyboard, but those descriptions conflict with the Foxboro P0924 product family. The most consistent identification for P0924WV is an I/A Series control processor module.

Quality Control Procedures

  • Part number verification: Confirm P0924WV, hardware revision, serial number and firmware version.
  • Visual inspection: Check connectors, PCB condition, labels, mounting hardware and ventilation areas.
  • Power check: Verify 24 VDC supply, polarity and power consumption before energizing.
  • Communication test: Validate Ethernet, ControlNet and RS-232 interfaces.
  • Redundancy check: If configured as a redundant pair, verify synchronization and failover behavior.
  • I/O bus verification: Confirm communication with associated FBM modules and fieldbus segments.
  • Documentation traceability: Record firmware version, configuration backup, test results and replacement history.

Frequently Asked Questions

What is the Foxboro P0924WV?
It is a Foxboro I/A Series control processor module used for process control, data acquisition and system communication in Foxboro DCS systems.
Is P0924WV a pressure transmitter?
No. Although some listings describe it as a transmitter, the P0924 family is associated with I/A Series control hardware. The transmitter description appears inconsistent with the Foxboro product line.
Can it support redundancy?
Yes. The module is described as supporting dual-module hot-standby redundancy in I/A Series systems, but the actual configuration depends on the installed system.
What communications does it support?
Typical interfaces include Ethernet 10/100BaseTX, ControlNet and RS-232.
Is it still in production?
Not confirmed. P0924WV is commonly available through surplus, refurbished or DCS spare-parts suppliers.

Installation and Configuration Guide

  1. Confirm identity: Check the module label for P0924WV, revision, serial number and firmware version.
  2. Back up configuration: Export the controller configuration and redundancy settings before removal.
  3. Isolate power: Follow plant lockout/tagout procedures before handling the module.
  4. Record slot position: Note the rack, slot number and associated FBM assignments.
  5. Replace the module: Install the P0924WV into the correct I/A Series processor slot.
  6. Restore communications: Reconnect Ethernet, ControlNet and RS-232 links as documented.
  7. Download configuration: Load the correct controller program and verify I/O mapping.
  8. Commission under supervision: Test control loops, alarms, redundancy failover and FBM communication before returning to normal operation.
