Digital Output Electrical Characteristics
The FS-TDO-1624 provides 16 digital output channels with a specified 24 VDC output rating. The maximum stated output current is 100 mA per channel. However, the permitted load must also comply with the specified lamp-load and capacitance limits.
The stated voltage drop is less than 1.2 VDC at 100 mA. This value describes the output circuit under the specified load condition. The connected device’s input characteristics and current demand should be checked before commissioning.
The module’s listed internal power requirement is 5 VDC at 35 mA. This supply specification should be distinguished from the 24 VDC field output rating.
Frequently Asked Questions (FAQ)
Q: How many digital output channels does the FS-TDO-1624 provide?
A: The supplied specifications identify 16 digital output channels.
Q: What are the maximum output current and lamp-load ratings?
A: The maximum stated output current is 100 mA, while the maximum lamp load is 50 mA (1.2 W). Confirm the applicable channel and load limitations in the manufacturer’s documentation before connecting field devices.
Q: Can the FS-TDO-1624 be treated as a safety-rated output module?
A: No. The supplied product description identifies it as a non-safe digital output FTA. Do not use it as a safety-rated output device without explicit confirmation of the applicable system configuration and safety certification.
Field Installation Guidelines
- Verify module compatibility: Confirm the FS-TDO-1624 hardware revision, terminal assembly compatibility, and applicable Honeywell system documentation before installation.
- Check field supply voltage: Verify that the connected output circuits use the specified 24 VDC rating and that the required system-side 5 VDC supply is available.
- Calculate output loading: Keep each channel within its documented current, lamp-load, and capacitive-load limits.
- Inspect wiring polarity: Confirm terminal assignments, field supply polarity, and load connections against the manufacturer’s wiring diagram.
- Separate signal and power wiring: Route digital output conductors separately from high-current switching and other noise-generating circuits where practical.
- Verify grounding and shielding: Apply the grounding and shield termination methods specified for the installed Honeywell system. Do not assume that every output conductor requires shielding.
- Test before commissioning: Verify output switching, load response, terminal integrity, and system diagnostics under controlled conditions.
