Product Details
The Foxboro P0916NB, also cataloged as the P0916NB Field Control Processor, operates as a dedicated hardware component for isolated signal processing and output control execution within Foxboro DCS architectures. It processes control loop signals and manages system memory using 16 MB SDRAM and 32 MB Flash memory while operating from a redundant 24 VDC power interface.

Channel-to-Channel Isolation and Loop Protocol Connectivity
The Foxboro P0916NB incorporates galvanic isolation barriers across its 8 output channels to prevent ground loops from interfering with field instrumentation. Internal signal paths preserve output accuracy when interfacing with 4-20 mA HART loop protocol field positioners, ensuring that control output commands remain unaffected by high common-mode noise or ambient thermal variations at the cold junction compensation (CJC) reference terminals.
Frequently Asked Questions
Q: What power redundancy features does the P0916NB module support?
A: The module accepts dual redundant 24 VDC power supply inputs to ensure uninterrupted processor operation in the event of a single power rail failure.
Q: What is the maximum power consumption of the P0916NB under full load?
A: Maximum power consumption is rated at 8.5 W per module in a non-fault-tolerant operating configuration.
Field Installation Guidelines
Ensure power supplies to the baseplate mounting position are isolated prior to installing or removing the P0916NB module. Inspect the backplane gold finger connectors and mechanical keying slots for contamination or physical damage before seating the module.
Slide the module into its baseplate slot until the locking latches click into place, securing electrical connection with the 24 VDC redundant power bus. Route field wiring conductors through dedicated cable raceways, maintaining separation between field output lines and high-voltage power cables. Verify that cabinet grounding wires are securely bonded to the main earth ground bar, and ensure all panel conduit entries achieve a minimum of 5 full threads of engagement on NPT fittings.

Tech & Buying Guide
Spatial Computing in Industrial Automation: Elevating PLC and DCS Operations with AR and VR
Industry 4.0 integrates digital intelligence into field operations, transforming factory automation landscapes worldwide. Spatial technologies—specifically Augmented Reality (AR) and Virtual Reality (VR)—redefine how engineers interact with industrial control systems. By bridging computer-generated CAD models with real-time operational technology (OT) data, immersive displays enable intuitive monitoring, rapid diagnostics, and safer maintenance across complex processing facilities.
Master Acceptance Testing: Understanding FAT and SAT in Industrial Control Systems
Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) serve as critical quality assurance gateways in complex industrial control systems. Both procedures verify that programmable logic controllers (PLCs), distributed control systems (DCS), and associated field devices meet strict functional specifications. However, executing these tests effectively requires clear delineation between off-site staging and final field commissioning.
Industrial Networking Essentials: Demystifying Hubs, Switches, and Routers in Control Systems
Industrial automation relies heavily on robust networking infrastructure to connect programmable logic controllers (PLCs), distributed control systems (DCS), and human-machine interfaces (HMIs). Modern factory automation environments generate vast amounts of real-time operational data across deterministic networks. Understanding the structural differences between hubs, switches, and routers ensures optimal traffic segmentation, minimizes latency, and maintains high network availability.
