Common Applications
Product Precautions
Designed for the documented Series 8 redundant output architecture, this IOTA keeps field termination and paired-module service organized within the controller assembly.
- Provides the redundant IOTA base for Series 8 analog-output assemblies
- Keeps field wiring on a removable modular termination structure
- Supports coated hardware selection for the documented Series 8 build
- Accommodates either HART-capable or non-HART analog-output IOM pairing
Mount 8C-TAOXB1 51307137-175 in the approved Series 8 redundant analog-output assembly and verify the paired IOM type before landing field conductors. Confirm field supply, channel assignments, redundancy status and configured safe-state behavior before placing outputs in service.
Important Notice: Verify the complete model and item number, the Series 8 carrier arrangement, both IOM hardware types, field terminal assignments, 24 Vdc supply, shield treatment, FAILOPT configuration, redundancy health and a controlled loop test before commissioning.

Redundant process-control outputs
Terminates paired analog-output channels used to command final control elements in a Series 8 controller installation.
HART device output architecture
Works with the documented HART analog-output IOM when the project requires digital device communication over the current loop.
Non-HART current-loop service
Provides the redundant IOTA foundation for conventional Series 8 analog current outputs.
Controller migration panel work
Supports controlled replacement of the IOTA while preserving the approved Series 8 wiring and redundancy design.
Read the applicable Honeywell installation information before work. Verify 8C-TAOXB1 51307137-175 and the installed Series 8 Redundant Analog Output IOTA configuration before isolation, wiring or commissioning.
1
Confirm both the 8C-TAOXB1 and 51307137-175 markings before work.
2
Isolate field power and place controlled outputs in a safe operating state.
3
Apply ESD controls before removing either redundant IOM.
4
Record terminal, shield and field-supply assignments before disconnecting conductors.
5
Match the replacement IOTA to the configured HART or non-HART IOM pair.
6
Inspect the modular field connectors and redundant mating positions before insertion.
7
Restore the configured redundancy and FAILOPT behavior before releasing outputs.
8
Prove each affected 4-20 mA loop under controlled commissioning conditions.
Technical notes
Mount 8C-TAOXB1 51307137-175 in the approved Series 8 redundant analog-output assembly and verify the paired IOM type before landing field conductors. Confirm field supply, channel assignments, redundancy status and configured safe-state behavior before placing outputs in service.
