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.
