Product Description

The Foxboro P0926GH is a versatile Fieldbus Communication Module (FCM) hardware platform supporting FBM224, FBM230, and FBM231 configurations. Equipped with four independent serial ports, this module enables high-speed integration between the I/A Series DCS and peripheral devices such as PLCs, weighing scales, and motor drives.

By leveraging software drivers, the P0926GH serves as a flexible protocol gateway, converting diverse serial communications into the native control system environment while maintaining strict electrical isolation.

Technical Specifications

Integration and Versatility

The P0926GH is the hardware backbone for serial integration in I/A Series systems. Depending on the loaded software driver, it can function as:

• FBM224 for Modbus Master communications

• FBM230/FBM231 for Field Device System Integrator (FDSI) roles

Its rugged design allows installation close to field devices, reducing serial cable length and improving signal reliability, while offloading communication tasks from the main control processor.

FAQ

Is the P0926GH a direct replacement for all three models?
The P0926GH is the physical hardware; its specific function is determined by the loaded software driver (FBM224, FBM230, or FBM231).

Does it support RS-485 multi-drop?
Yes. When configured for RS-485, each port can communicate with multiple slave devices on a daisy-chained loop.
