Foxboro P0916AC – I/A Series Safety-Certified Redundant Processor Module

In stock

Product Introduction:
The Foxboro P0916AC is a safety-certified redundant processor module for the Foxboro I/A Series Distributed Control System. The “P” denotes Processor, “0916” identifies the high-availability processor family, and “AC” indicates the “AC” revision, which is specifically certified for safety-critical applications up to SIL 3 (Safety Integrity Level 3) per IEC 61508 and IEC 61511. This module is the safety processor in a Foxboro safety instrumented system (SIS), executing safety logic that protects people, equipment, and the environment from hazardous events. The P0916AC features true dual-redundant architecture with hardware voting, diagnostics coverage exceeding 99%, and fail-safe output design. Every output defaults to a safe state (de-energized) on any failure condition. The “AC” revision includes enhanced safety diagnostics, proof test capabilities, and compliance with the latest functional safety standards, making it the processor of choice for the most demanding safety applications in oil and gas, chemical, and power generation.

Functional Features:
SIL 3 Certified: Certified to the highest safety integrity level for process industry applications.
Hardware Voting: 2-out-of-3 hardware voting on every safety scan cycle; if one processor disagrees, it is automatically taken out of service.
99% Diagnostic Coverage: Detects and reports over 99% of all potential dangerous failures, satisfying the most stringent safety standards.
Fail-Safe Outputs: All safety outputs default to a safe state (de-energized) on any failure condition, including loss of power, loss of communication, or processor fault.
Proof Test Capability: Supports online proof testing of safety loops without shutting down the process.
Safety Communication: Uses dedicated safety communication protocols (PROFIsafe, Modbus TCP Safety) that are separate from the standard control network, ensuring that safety data is never compromised by non-safety traffic.
