Features:
- Digital Output Module for the documented Triconex fault-tolerant safety systems.
- Points: 16, commoned.
- Nominal output voltage: 24 V DC.
DO3401 S2 belongs to the Triconex fault-tolerant safety systems and performs the documented digital output module role in the Triconex Tricon and Trident safety architecture. The retained technical evidence records Points: 16, commoned; Nominal output voltage: 24 V DC; Operational voltage range: 15–30 V DC. 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 DO3401 S2 Digital Output Module is supplied only after the complete hardware identity, condition and current OEM lifecycle status have been confirmed.
DO3401 S2 Triconex product documentation and selection resources.
Important Notice: The uploaded PDF documents the listed model or its identified Triconex product 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: DO3401 S2 performs the digital output module function within the Triconex fault-tolerant safety systems. The retained documentation identifies points as 16, commoned; 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.
Rack Matching: approve DO3401 S2 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.
Startup Checks: isolate the equipment, remove stored energy and inspect the receiving hardware before installing DO3401 S2.
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.
