Product Description

The P0926GV is a high-reliability External Termination Assembly (ETA) engineered for use with the Foxboro I/A Series FBM242 architecture. It provides the critical physical interface between field wiring and discrete output modules, with specific design support for redundant I/O configurations.
By implementing the P0926GV, industrial control systems can eliminate single points of failure, ensuring continuous process control even during module faults or maintenance activities.

The assembly incorporates full channel-to-channel galvanic isolation, preventing electrical faults, surges, or ground loops on one field circuit from affecting adjacent channels or the system backplane. Its ruggedized design supports DIN-rail mounting within control cabinets, offering a reliable and serviceable termination point for field wiring.

Technical Specifications

Application

The P0926GV is intended for mission-critical discrete output applications, including:

• Emergency Shutdown Systems (ESD)

• Burner management and safety interlock systems

• Continuous chemical and petrochemical process units

In redundant configurations, the ETA ensures uninterrupted field device control even if one FBM242 module is removed or fails, maintaining process availability and safety integrity.

Frequently Asked Questions

Q: Does the P0926GV require individual channel fusing?
A: The assembly operates in conjunction with the FBM’s internal protection. External fusing is recommended for high-energy or site-specific field circuits.

Q: Can the P0926GV be used in non-redundant systems?
A: Yes. While optimized for redundant architectures, it may also be used in single-module applications where enhanced isolation and termination robustness are required.
