Features:
- Provides one 24 VDC de-energize-to-act discrete output channel.
- Designed for the DeltaV SIS Logic Solver CHARM architecture.
- Supports safety shutdown and compatible final-element control circuits.
The current ordering configuration is SS4302T01, the DeltaV SIS LS 24 VDC DTA Discrete Output CHARM.
It drives a de-energize-to-act safety output for shutdown functions where the defined safe action removes output energy.
Before commissioning, confirm the DTA philosophy, field-load requirements, terminal assembly, and approved proof-test procedure.
Availability is subject to Apter Power inventory and sourcing confirmation.

- Drive a single 24 VDC de-energize-to-act safety output through an LS CHARM channel.
- Implement safety shutdown final-element circuits whose defined safe action removes output energy.
- Use Electronic Marshalling to assign the output channel to the corresponding CSLS safety logic.
- De-energize-to-act operation supports safety functions whose safe state removes output energy.
- The 24 VDC field circuit must match the documented load and terminal requirements.
- Complete the approved loop proof test before returning the safety function to service.
- Use DeltaV SIS channel diagnostics to verify the output path and connected field circuit.
- Investigate commanded-state and final-element response differences during commissioning or proof testing.
- Record diagnostic findings and proof-test results under the site safety lifecycle procedure.
- Install the CHARM with the matching Logic Solver terminal assembly and documented 24 VDC field circuit.
- Confirm load polarity, wiring, and de-energize-to-act behavior before energizing the loop.
- Follow site power-isolation and hazardous-area procedures before insertion, removal, or wiring changes.
