Features:
- Sixteen fail-to-safe 24 V DC inputs
- Defined HIGH and LOW thresholds
- Protected 24 V diagnostic test output
FC-SDI-1624 converts field contact states into supervised digital input data for a Honeywell Safety Manager safety application.
The termination assembly, test circuitry and application mapping must be validated together because module installation alone does not prove the complete safety input loop.
Field voltage, test-output wiring and application channel mapping should be proven together during commissioning of every safety-related input.
The Honeywell FC-SDI-1624 16-Channel Safe Digital Input Module is available for quotation and technical support from Apter Power.
Verified resources for FC-SDI-1624:
Input Data:
- 16 channels at nominal 24 V DC
- HIGH above 15 V DC
- LOW below 9 V DC and 2 mA
The typical 10 ms input delay should be included in the application response-time assessment.
Output Data:
- 24 V DC diagnostic test output
- Short-circuit protected
- Maximum 450 mA
Wire the test supply exactly as shown for the selected termination arrangement.
System Matching:
- Key coding A5/C5
- Match the specified FTA and cable
- Verify redundant or non-redundant wiring
Confirm the complete input-loop design before landing field conductors.
Installation Check:
- Prove each HIGH and LOW state
- Verify test detection and channel diagnostics
- Confirm application channel mapping
Complete the site functional test before returning the safety loop to operation.
