Product Description

The Triconex 3501E  implements full TMR architecture with three isolated input channels that independently scan, process, and send data to the main processors.

Input data is voted before processing to ensure maximum safety and availability. All critical signal paths are fully triplicated.

The module supports 90–155 VAC/VDC, with per‑point LED status indicators and comprehensive online diagnostics.

It maintains operation under single faults and many multiple fault conditions, with module‑level fault and active status indication.
