Triconex P0916DG – TriStation Safety Controller Processor Module (Part P0916DG)

In stock

Product Introduction:
The Triconex P0916DG is a processor module for the Triconex TriStation 3008 safety controller. The “P” denotes Processor, “0916” identifies the specific processor configuration (typically a single-channel or dual-channel processor depending on the exact variant), and “DG” indicates the specific firmware or hardware revision. This module executes the safety application logic, performs the 2-out-of-3 voting, and communicates with all I/O modules via the TMRnet dual-redundant network. It is one of the three identical processors in a Triconex safety system, and all three must agree on every scan cycle for the system to operate. The P0916DG is a proven, field-tested processor used in thousands of safety systems worldwide.

Technical Specifications:
Board Type: Safety Controller Processor Module

Form Factor: 3U Triconex Eurocard

Functional Features:
Safety Logic Execution: Runs the safety application program that monitors process variables and initiates shutdown actions when unsafe conditions are detected.
Hardware Voting: Compares results from all three processors every 50ms; if one disagrees, it is removed from service automatically.
Dual Communication: Every processor has two independent communication paths to every I/O module, ensuring no single point of failure.
Online Diagnostics: Continuous self-testing with automatic fault detection and alarm reporting.
Fail-Safe Outputs: All safety outputs default to a safe state (de-energized) on loss of power or communication.
Application Flexibility: Supports complex safety logic including timers, counters, logic gates, and analog comparisons.
