Features:
- Redundant 18-inch Speed Protection IOTA assembly engineered for Honeywell Experion PKS Series C controllers.
- Processes 4 high-speed rotational sensor channels accepting passive (150 Hz to 25 kHz) and active (1 Hz to 10 kHz) inputs.
- Provides onboard active sensor excitation power with field-selectable 5 VDC or 24 VDC output settings.
The Honeywell CC-TSP411 51306669-175 is configured as an 18-inch redundant I/O Termination Assembly designed for interfacing CC-PSP401 speed protection modules within Series C cabinet environments.
This speed protection assembly executes a 2.5 ms scan rate to condition rotational speed inputs, perform high-speed trip calculations, and actuate four integrated isolated relay contacts for emergency machinery interlocks.
Verify jumper settings for active sensor excitation voltage prior to power-up, and ensure secure shield grounding on the heavy-duty terminal blocks to prevent electromagnetic interference.
The Honeywell CC-TSP411 51306669-175 is available as genuine new surplus and fully tested replacement hardware supplied with commercial support by Apter Power, independent of original warranty commitments by the manufacturer (OEM).
