Features:
- 32 discrete digital input points commoned in groups of 8.
- Integrated hardware switch mechanism for automated stuck-On failure diagnostic testing.
- 100% triplicated signal conditioning pathways across three physically isolated channel buses.
Standard order configuration supplies the Triconex 3502E digital input module built with triple modular redundancy for critical logic processing.
This digital input processing board operates within Tricon main or expansion chassis backplanes to evaluate field contact states for safety instrumented systems.
Installation requires selecting an appropriate external termination panel with compatible interface cabling, ensuring mechanical slot keying matches the 24 VAC/VDC TMR profile prior to chassis insertion.
The Invensys Triconex 3502E module is guaranteed to be fully functional, fully tested, and refurbished by the manufacturer (OEM).
