Product Introduction
FOXBORO P0926KN is a control processor module for the I/A Series DCS platform. It manages process variables and executes logic for industrial automation.This module uses a 32-bit RISC processor with 8 MB program memory. It handles 0.1 µs boolean instructions and supports redundant power configurations for continuous operation.
Installation & Configuration Guide
Preparation
Gather your 24 VDC power supply and wiring tools. Verify the FOXBORO P0926KN matches your system’s required revision. Clear the installation slot of any debris or obstructions.Removal
Power down the system completely. Disconnect all wiring from the existing module. Release the locking mechanism and carefully extract the old unit. Inspect the backplane connector for bent pins.Installation
Align the FOXBORO P0926KN with the backplane guides. Slide it in firmly until fully seated. Engage the locking mechanism to secure the module. Reconnect all field wiring according to the schematic.Power-On & Test
Restore 24 VDC power to the system. Monitor the module status LEDs for normal operation. Check the DCS software for communication with the new processor. Verify process data is updating correctly.
Troubleshooting Quick Reference
- No Power LED: Check 24 VDC supply at terminal block. Measure voltage; must be 24 VDC ±10%.
- Comm Fault LED: Verify network cable connections. Check IP configuration matches system settings.
- Erratic Process Data: Inspect field wiring for shorts or ground faults. Test I/O modules separately.
- Module Won’t Boot: Reseat the module in the backplane. Check for firmware version mismatch.
- Overheat Warning: Verify cabinet cooling fans are operational. Check ambient temperature is below 60°C.
Dimensions, Mounting & Wiring Notes
- Dimensions: 140 mm (H) x 165 mm (W) x 45 mm (D)
- Mounting: Standard I/A Series backplane slot
- Wiring: 24 VDC power input on dedicated terminals. Network connections via standard industrial connectors.
FAQ
Can I use this FOXBORO P0926KN in a redundant system?
Yes. The module supports hot-standby redundancy with bit-level matching. Both CPUs run in RUN mode for millisecond-level failover.I received the module, but the revision doesn’t match. What now?
Stop. Do not install it. Different revisions may have incompatible firmware or hardware. Contact us immediately with your order number and the revision on the old module.Is this a refurbished unit?
No. This is New Original (New Surplus) stock. It has never been installed in a field system. We perform full functional testing before shipment.What’s the lead time if it’s not in stock?
Typically 3-5 business days from our warehouse. We maintain strategic inventory for critical I/A Series spares. Expedited shipping is available.How do I know this isn’t a counterfeit?
Every unit includes a traceable serial number. We verify against manufacturer records. You can request photos of the actual unit before purchase.Will my existing program work with this replacement?
Usually yes, if the revision matches. We recommend backing up your current configuration first. Firmware differences between major revisions may require program updates.I installed it but get a comm error. Help?
First, check the physical network connection. Then verify the module’s IP address hasn’t defaulted. Finally, confirm the backplane slot matches your software configuration.
