Description
The Triconex 3006 is an EMP II Main Processor Module used in Tricon safety instrumented systems. It is designed for Tricon v9.0–v9.5 systems and provides the central processing function for safety and control logic. The 3006 uses a fault-tolerant architecture with dedicated communication and I/O processors, dual power regulation, and TriBus communication.
The processor is based on a National NS32GX32 32-bit CPU running at 25 MHz, paired with an NS32381 floating-point processor. Compared with the closely related Model 3007, the 3006 provides 2 MB SRAM, while the 3007 uses 1 MB.
The module is intended for legacy Tricon safety-control installations where deterministic processing, fault tolerance, and continuous system availability are important. It is commonly maintained as a replacement or spare processor for existing Tricon systems.

- Legacy Tricon safety systems
Installation & Use
- Verify the processor model — Confirm 3006 and the installed Tricon system version before replacement. The 3006 is documented for Tricon v9.0–v9.5 systems.
- Check the processor configuration — Verify the processor position, firmware, application configuration, and existing processor set before installation.
- Inspect the chassis — Check the backplane connector, power contacts, grounding, and processor seating for contamination or mechanical damage.
- Check battery-backed resources — The processor contains clock/calendar and battery-backed memory functions. Verify the battery condition during maintenance.
- Power-up diagnostics — After installation, check the front-panel status indicators and verify that the processor reaches its normal operating state.
- Communication test — Verify TriBus communication, diagnostic communication, and the fault-tolerant I/O/communication paths.
- System validation — Confirm processor synchronization, I/O status, alarms, diagnostics, and safety logic execution before returning the system to service.
⚠️ Replacement note: The 3006 and 3007 are similar but are not identical—the primary documented difference is SRAM capacity: 2 MB for the 3006 versus 1 MB for the 3007. Do not substitute between them without checking the Tricon system configuration and applicable documentation.
