More Information

Overview Manuals Applications Monitoring & Control Compatibility & Interoperability Compliance

Features:

  • Provides four controlled analog output channels.
  • Accepts redundant 24 VDC loop-power sources through compatible baseplates.
  • Supports HART multiplexing with the designated 2483-series baseplates.
The 3481S2 is the four-point analog-output member used in standard and HART Tri-GP assemblies.

Triplicated selector logic drives each channel while current loopback supports controller diagnostics.

Baseplate identity, loop supply, load resistance, HART wiring and unused-point jumpers must be verified.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Commands valve positioners and other 4–20 mA final elements.
  • Provides HART maintenance access through the 4850 multiplexer arrangement.
  • Feeds hazardous-location isolators from the approved energy-limiting termination assembly.
  • Each output uses selector logic and current loopback to supervise the commanded signal.
  • Four independent points serve separate current-loop final elements.
  • The controller reports module or channel abnormalities through the Tri-GP diagnostic path.
  • The direct 2481S2 baseplate supports the standard four-point output arrangement.
  • HART operation uses 2483S2 or 2483AS2 with the Triconex 4850 multiplexer.
  • The hazardous-location 9863-610F panel accepts four active outputs even though it provides eight terminal positions.
  • Hazardous-location assemblies use the approved baseplate, isolators and energy-limiting termination design.
  • ATEX installations require the documented intrinsic-safety isolators and wiring practice.
  • Certification applies to the complete approved assembly rather than the output module alone.
Description
Triconex 3481S2 provides four current-output channels for final elements and analog interfaces. Each point receives triplicated command paths through selector logic and a dedicated digital-to-analog converter arrangement. Four current-loop outputs use A, B and C channel logic, individual conversion paths and current feedback to support voted analog control.

The module can be used with the 2481S2 direct baseplate, 2483S2 HART baseplate or the corresponding hazardous-location assemblies. HART versions add the Triconex 4850 multiplexer and filtered communication path without changing the four active output count. Standard and HART-capable baseplates extend the same module into conventional or asset-management loops while retaining redundant 24 VDC loop power.

Preserve redundant 24 VDC loop power, correct load polarity and the requirement to short unused active output positions. The HART baseplates are limited to 3481S2; fitting another module can damage baseplate components. Hazardous-location termination adds protective-earth and unused-point requirements that must be reflected in cabinet construction and commissioning records.

Technical notes
2483S2 and 2483AS2 HART baseplates are approved only for 3481S2; installing another output module can damage the baseplate.
