Description
The Foxboro P0926KE (also identified as RH926KE) is a 2-position modular baseplate engineered for the Foxboro I/A Series and Foxboro Evo process automation systems. This baseplate serves as a critical mounting platform and communication backplane for 200 Series Fieldbus Modules (FBM) and Field Communications Modules (FCM). Designed for high-reliability industrial environments, it supports seamless integration and hot-swapping of modules, allowing for maintenance without interrupting field wiring or system power.
Features
- Supports up to two 200 Series FBM or FCM modules.
- Passive backplane architecture for enhanced system reliability.
- Redundant 24 VDC power input connections for high availability.
- Integrated module guides for precise alignment and protection of electrical contacts.
- Supports 2 Mbps redundant Module Fieldbus (HDLC) communication.
- Fixed baseplate addressing (Baseplate 0) with slots 1 and 2.
Applications
This baseplate is widely utilized in distributed control environments, including oil and gas refining, power generation, and large-scale mining operations where modular, high-availability I/O configurations are required.

Installation Guidelines
- Ensure the DIN rail is securely mounted and grounded according to local electrical codes before installing the baseplate.
- The baseplate is designed for horizontal mounting; ensure adequate clearance for airflow and module insertion/removal.
- Handle with care to avoid ESD damage to the backplane connectors.
- Verify that the 24 VDC power supply is properly connected to the redundant terminals to ensure system availability.
- Modules may be hot-swapped; however, always ensure the module is fully seated and locked into the guide rails to prevent contact misalignment.
