Overview
The Honeywell FS-TSDO-0824, also cataloged as the TSDO-0824 Safe Digital Output Field Termination Assembly (FTA), provides the electrical interface between SDO-0824 safe digital output modules and external field wiring in Honeywell Safety Manager systems. It supports eight digital output channels in a 24 VDC system architecture and connects to a redundant pair of output modules through the SICC-0001/Lx system interconnection cable.

Safety Manager Digital Output Interface Characteristics
The FS-TSDO-0824 terminates field wiring for the SDO-0824 safe digital output modules. Its eight-channel configuration supports the connection of external loads to the associated output circuitry. The specified maximum continuous current is 1.5 A per channel, while the maximum stated voltage is 36 VDC.
For redundant configurations, the FTA connects to a pair of SDO-0824 output modules through the SICC-0001/Lx interconnection cable. The applicable system configuration determines the output behavior and fault response. The available specifications do not establish channel-to-channel galvanic isolation, individual channel fuse ratings, switching time, or the detailed fail-safe response; these values require confirmation from the applicable Honeywell documentation.
Frequently Asked Questions (FAQ)
Q: How many digital output channels does the FS-TSDO-0824 support?
A: The assembly supports eight digital output channels in a 24 VDC system architecture.
Q: What are the maximum voltage and continuous current ratings?
A: The stated maximum voltage is 36 VDC, and the maximum continuous current is 1.5 A per channel. Confirm the output module and system load limits before connecting field devices.
Q: What wiring specifications apply to field connections?
A: The maximum stated wire diameter is 2.5 mm2 (AWG 14). Strip 7 mm of insulation and apply a tightening torque of 0.5 Nm (0.37 ft-lb).
Field Installation Guidelines
- Verify the FS-TSDO-0824 model and compatibility with the installed Honeywell Safety Manager hardware.
- Isolate the relevant power sources and follow the site’s approved safety procedures before making wiring changes.
- Connect the assembly to the designated SDO-0824 output modules using the specified SICC-0001/Lx interconnection cable.
- Identify each field conductor against the approved wiring diagram before terminating the eight output channels.
- Keep field wiring separated from high-noise power conductors where practical. Apply cable shielding and grounding according to the system installation documentation.
- Observe the specified 7 mm strip length, 2.5 mm2 maximum wire diameter, and 0.5 Nm tightening torque.
- Verify conductor retention, wiring polarity, load ratings, and terminal assignments before restoring power.
- Perform the prescribed functional and safety checks before returning the associated control loop to service.
