8C-TDODA1
Honeywell Series 8 Digital Output 24 VDC I/O Module
Product Profile
8C-TDODA1 is the Series 8 bussed 24 VDC digital output module shown in Honeywell official specifications as a 32-channel, non-redundant 9-inch coated IOTA model. It is paired with an optional redundant 12-inch variant and a relay extension option.

System Role
Control output function
- Provides 32-point 24 VDC switched outputs for solenoids, contactors, and digital field actuators.
- Supports direct, reverse, latched, pulse, and PWM output behavior on a per-channel basis.
- Designed as part of Series 8 I/O architecture where internal diagnostics and module diagnostics are expected in critical control loops.
Safety and operation behavior
- Fail-safe behavior is configurable per channel through FAILOPT logic.
- Supports powered hot insertion and removal as part of module lifecycle operation.
- Supports relay conversion through the dedicated relay extension board when dry contact output is needed.
Compatibility
- Family equivalent in same I/O family: 8C-TDODB1 (redundant 12-inch bussed DO).
- Relay extension compatibility: 8C-SDOX01 (relay extension board) for dry-contact applications.
- Function-matrix role aligns with non-redundant DO source model 8C-PDODA1 and IOTA 9-inch DO architecture.
Applications
- Process modules needing discrete digital output control and quick switching at plant-level speeds.
- Valve, relay, and interposing contact interfaces where per-channel fail-safe behavior is required.
- Distributed control cabinets using Honeywell Series 8 controller and IOTA expansion design.
FAQ
What is 8C-TDODA1’s role in the Series 8 portfolio?
It is the non-redundant coated 9-inch I/O module for 24 VDC bussed digital outputs, with 32 channels.
How does failure response behave during module control?
The module supports FAILOPT per channel with HOLD THE LAST VALUE or SHED TO SAFE VALUE options.
Can I switch from 8C-TDODA1 to a relay output style?
Yes. A relay extension workflow is supported through 8C-SDOX01, as specified in the official Series 8 DO Relay Extension section.
Can this module be removed or inserted while powered?
Yes. Module insertion/removal under power is supported.
What is the electrical loading limit for channels?
Each channel supports 100 mA maximum, and the module supports up to 3.2 A total per module maximum.
Is there a published EOL or replacement model specifically for 8C-TDODA1?
No dedicated EOL stop-date or official replacement note for this exact model was found in the retrieved official Honeywell Series 8 specification package. For project risk decisions, request lifecycle confirmation from Honeywell support or lifecycle service channels.
