Features:
- Terminates thirty-two high-voltage digital inputs for the S100 I/O system.
- Separates the field circuits into four isolated groups of eight channels.
- Supports the documented 110 V DC or 120 V AC DSDI 110A configuration.
The spare identity combines ABB type DSTD197 with product ID 3BSE004726R1.
It provides grouped field termination for discrete status acquisition through compatible S100 input hardware.
Verify voltage, group commons, DSDI board, cable, terminal map, and product label before installation.
Availability is subject to Apter Power inventory and sourcing confirmation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Connect 110 V DC or 120 V AC equipment-status contacts to an S100 input subsystem.
- Maintain isolated input grouping in an existing Advant Master process-control cabinet.
- Replace a damaged termination unit after high-voltage sources and associated cables are verified.
- Thirty-two field inputs are arranged as four groups containing eight channels each.
- Electrical isolation between groups allows separate field commons within the documented design.
- Preserve each common and terminal assignment when transferring the field conductors.
- The paired S100 input electronics scan the terminated discrete process states.
- Interrupt or event handling depends on the configured DSDI hardware and controller application.
- Commissioning should prove both logic states and the expected time/event behavior for every used input.
- Install the unit in the specified S100 cabinet environment with suitable protection from contamination and moisture.
- Maintain insulation clearances appropriate to the 110 V DC or 120 V AC field circuits.
- Inspect connectors, terminals, and cable strain relief for heat or mechanical damage before energizing.
