PRODUCT DESCRIPTION
DO3401 TMR digital output module
Triconex DO3401 is a triple-modular-redundant digital output module for Tricon safety and critical-control systems. Family documentation identifies sixteen commoned 24 V DC output points with loop-back diagnostics and field power or short-circuit alarm supervision.
The base DO3401 identity must be checked separately from later suffix variants such as S2. Match the installed chassis, field termination, output load and project configuration, then prove every safety function under the approved management-of-change and test procedure.
