Triconex 8300A Power Supply Module
– Product Description
The Triconex 8300A Power Supply Module is a critical component of the Tricon controller system, designed to deliver high-reliability, dual-redundant power to support safety-critical applications. Engineered to provide fault-tolerant performance, the 8300A module ensures uninterrupted operation of the Triconex main chassis and all installed modules, even in the event of a power module failure.
Each main chassis in a Tricon system supports two 8300A power supply modules working in parallel. Both units feed independent power rails and feature built-in diagnostics, allowing the system to isolate faults without affecting the operational integrity of the controller. This module plays a vital role in the Triconex system’s SIL3-certified architecture, widely adopted in industries demanding maximum safety and availability.
