Product Description

The P0916QD is a Redundant Adapter / Interface Module for the Foxboro I/A Series 200 Series FBMs. It provides the physical and electrical bridge enabling two Fieldbus Modules to operate as a synchronized redundant pair, ensuring continuous control in mission-critical loops even if the primary module fails.

The module manages signal routing and impedance matching between redundant modules and the External Termination Assembly (ETA), preventing signal glitches during failover events. Its compact, high-density design allows direct mounting on Foxboro baseplates, providing a reliable and space-efficient solution for critical I/O points in industrial control cabinets.

Technical Specifications

Application

The P0916QD is used in high-availability control loops where process continuity is critical, including:

• Chemical refining units

• Nuclear power generation

• Safety-critical temperature, pressure, or valve control loops

It is essential in redundant module architectures, allowing secondary modules to maintain control during primary module failure, minimizing downtime and preventing process trips.

Frequently Asked Questions

Q: Do I need a P0916QD for every FBM?
A: No. The adapter is only required for loops where redundant module pairs are implemented to improve system reliability.

Q: Is the P0916QD compatible with older 100 Series hardware?
A: No. The P0916QD is designed specifically for the 200 Series I/O subsystem, both mechanically and electrically.
