The Foxboro P0926KE (also identified as RH926KE) is a 2-position modular baseplate engineered for the Foxboro Evo and I/A Series distributed control systems. This baseplate serves as the foundational mounting interface for 200 Series Fieldbus Modules (FBMs) and Field Communications Modules (FCMs). By providing a passive backplane architecture, it facilitates reliable communication and power distribution in demanding process automation environments, including oil and gas, chemical processing, and power generation facilities.
Features
Supports up to two FBM or FCM modules in a compact 2-position configuration.
Features a 2 Mbps redundant Module Fieldbus for high-speed data transfer.
Designed with integrated module guides to ensure correct alignment and protection of electrical contacts during installation or hot-swapping.
Hardwired baseplate addressing (Baseplate 0) with fixed slot assignments for simplified system configuration.
Supports redundant 24 VDC power inputs to ensure high availability and operational continuity.

Installation Guidelines
Ensure the DIN rail is securely mounted and leveled before attaching the baseplate.
Always power down the system segment before attempting to install or remove the baseplate from the rail to prevent electrical arcing.
Verify that the redundant 24 VDC power supply connections are polarity-correct to avoid damage to the backplane circuitry.
Maintain adequate clearance around the unit to allow for heat dissipation, adhering to specified operating temperature limits.
Use caution when inserting modules; the integrated guides are designed to prevent misalignment, but force should never be used if resistance is encountered.
FAQ
Can I perform a hot-swap with this baseplate? Yes, the P0926KE baseplate is designed to support the hot-swapping of 200 Series modules, allowing for replacement without disconnecting field wiring or shutting down the entire system power.
What is the baseplate address for this unit? This 2-position model is hardwired for Baseplate 0, with FBM slots designated as 1 and 2.
