Core Architecture and Processing Capability
The Triconex 3008 executes control logic across three isolated microprocessors. This main processor module uses a 32-bit RISC architecture for high-speed calculations. It simultaneously compares all output results from each processor leg. Consequently, the system detects and masks any single hardware fault.
Technical Specifications and Physical Dimensions
This processor module measures 330 mm in overall length. Its width reaches 210 mm for a full-height chassis slot. The board depth stands at 45 mm including the backplane connector. You will find 2,150 discrete components on this complex PCB. These components include custom ASICs, memory chips, and power regulators. The module weighs approximately 1.4 kilograms for solid mechanical stability.
Memory Configuration and Energy Storage
The Triconex 3008 contains 4 MB of battery-backed SRAM. A replaceable lithium coin cell preserves this data during power loss. This battery provides a typical retention period of five years. Additionally, the module holds 8 MB of flash memory for firmware storage. The board uses four 100 µF tantalum capacitors for input filtering. However, these capacitors do not retain user data.
Interface Ports and Connectivity
Two RS-232 serial ports support local engineering access. A single RS-485 port handles the Tricon communication bus. Furthermore, six front-panel LEDs indicate processor health and synchronization. The module includes a 48-pin DIN 41612 backplane connector. This connector transfers power and I/O data simultaneously.

Operational Notes and Installation
You must install this processor in a Tricon chassis slot 1 or 2. The module synchronizes with a second 3008 for full 3-2-0 redundancy. Always replace the lithium battery during scheduled maintenance every four years. Verify that the backplane connector aligns perfectly before seating the card. The unit operates reliably from 0°C to 60°C ambient temperature.
