Features:
- Analog Input Modules for the documented Triconex fault-tolerant safety systems.
- Voltage: 0 to 5 VDC or -5 to +5 VDC, + 6%.
- No. of Input Points: 32 differential, DC-coupled.
3721N belongs to the Triconex fault-tolerant safety systems and performs the documented analog input modules role in the Triconex Tricon and Trident safety architecture. The retained technical evidence records Voltage: 0 to 5 VDC or -5 to +5 VDC, + 6%; No. of Input Points: 32 differential, DC-coupled; Input Update Rate: 10 ms. The full marking, receiving hardware, connectors or terminals, configuration dependencies and installed position must be matched before substitution.
For installation, retain the Triconex fault-tolerant safety systems receiving position, connector or terminal arrangement and configuration record. After power restoration, review diagnostics and test the affected operating path before process release.
The 3721N Analog Input Modules is supplied only after the complete hardware identity, condition and current OEM lifecycle status have been confirmed.

Important Notice: The linked document or internal product-family information must identify the listed model or its documented family. Confirm the complete order code, hardware revision and installed-system requirements before replacement. Accessories, cables, software and certificates are included only when stated in the quotation. All prices are shown in USD.
Signal Mapping: 3721N performs the analog input modules function within the Triconex fault-tolerant safety systems. The retained documentation identifies voltage as 0 to 5 VDC or -5 to +5 VDC, + 6%; apply that value only to this documented execution.
Match the complete label, hardware form and functional position before transferring any setting, cable or termination from the removed unit.
Integration Fit: approve 3721N only for the documented Triconex Tricon and Trident safety architecture. Compare rack, carrier or panel generation, connector keying, terminal numbering and all paired assemblies with the installation drawings.
Photograph both sides and the installed position before removal so revision markings, jumpers, addressing and channel allocation can be reconstructed accurately.
Service Checks: isolate the equipment, remove stored energy and inspect the receiving hardware before installing 3721N.
Restore power in the approved sequence, review status and diagnostics, then test every affected control, signal, relay, communication, protection or monitoring path against the commissioning record.
