Selection Guide
Use the following criteria to determine whether the 1444-DYN04-01RA is the right module for your application:
- Channel Count: Need 4 dynamic channels → 1444-DYN04-01RA ✓ | Need 8 channels → consider 1444-DYN08-01RA
- Sensor Type: ICP/IEPE sensors → 1444-DYN04-01RA ✓ | Proximity probes → consider 1444-ACNR series
- Frequency Range: Up to 20 kHz → 1444-DYN04-01RA ✓ | Ultra-high frequency (>20 kHz) → evaluate NI or B&K alternatives
- Integration: Native ControlLogix/Studio 5000 → 1444-DYN04-01RA ✓ | Open protocol/third-party SCADA → consider alternatives
- Budget: OEM pricing available via Konmask for both new and refurbished units
