Frequently Asked Questions

What types of pulse transmitters can I connect?

The DP820 supports RS422, 5V, 12V, 24V, and 13mA transducers. This covers most industrial encoder and sensor types available.

How accurate is the frequency measurement?

Measurement error remains below 100 ppm across the entire frequency range. This ensures reliable data for critical control applications.

Can I measure position and speed at the same time?

Yes, each channel performs simultaneous pulse counting and frequency measurement. This provides both position and speed data concurrently.

What is the maximum cable length allowed?

You can run field cables up to 200 meters. Use proper shielding to maintain signal integrity over long distances.

How do I troubleshoot communication issues?

Check the front panel LEDs first. The Pulse, Direction, and Strobe indicators show real-time channel status and help diagnose problems quickly.
