Overview
The Honeywell FC-TSDO-0824, also identified by the base model TSDO-0824, is a safe digital output module for discrete signal switching in Honeywell control and safety system applications. The module provides 8 output channels for 24 VDC field circuits. Associated field termination assembly (FTA) information specifies relay-based switching for AK5/6 applications; however, the exact relay configuration and compatibility with this model require confirmation against the applicable hardware documentation.

Digital Output and Safety Interface Characteristics
The FC-TSDO-0824 provides eight discrete output channels for field control circuits. The specified nominal field voltage is 24 VDC, with a maximum continuous current of 1.5 A per channel.
For installation, verify the field load current, supply voltage, wiring cross-section, and terminal assignment against the module’s applicable technical manual. The supplied FTA description also lists 2 A, 30 VAC, and 42 VDC ratings for relay applications. These values should not be treated as confirmed FC-TSDO-0824 output ratings without documentation establishing the relationship between the module and that specific termination assembly.
As a safety-related output device, its application must follow the approved system configuration and documented safety requirements. The listed approvals do not independently establish a specific SIL rating or prove compatibility with every Honeywell safety platform.
Frequently Asked Questions (FAQ)
Q: How many output channels does the FC-TSDO-0824 provide?
A: The supplied specifications identify eight digital output channels operating at a nominal field voltage of 24 VDC.
Q: What is the maximum continuous current per output channel?
A: The supplied specification lists 1.5 A per channel. Confirm the permissible load and any derating requirements in the applicable hardware manual before connecting field devices.
Q: Can the module be used with a relay-based FTA rated at 2 A?
A: The supplied FTA description mentions relay applications and a 2 A rating, but it does not establish the exact compatible FTA model or confirm that this rating applies to the FC-TSDO-0824. Verify the module-to-FTA compatibility and electrical ratings before installation.
Field Installation Guidelines
- Verify hardware compatibility: Confirm the module model, termination assembly, terminal assignments, and system compatibility against the approved Honeywell documentation.
- Check field power: Verify that the DC supply matches the specified 24 VDC nominal field voltage and remains within the documented operating limits.
- Size the wiring: Use conductors suitable for the connected load and terminal hardware. Do not exceed the specified maximum wire diameter of 2.5 mm2.
- Check output loading: Calculate the load current for each channel and confirm that the total loading complies with the module and system power limitations.
- Separate signal wiring: Route field output conductors separately from high-voltage and high-noise wiring where practical. Follow the cabinet grounding and shielding requirements specified by Honeywell.
- Validate safety functions: Perform the prescribed commissioning and functional tests before placing the output circuits into service. Do not assume a particular fail-safe state without consulting the approved system documentation.
