Important Notes
-
Designed for DC loads only. Do not connect AC mains loads.
- Use an external power supply suitable for the connected load.
- The module's input and output circuits should not be assumed to provide galvanic isolation.
- Use suitable flyback protection when switching inductive loads such as motors, pumps, and solenoids.
- For currents above 5A, additional cooling may be required.
- The advertised 20A maximum should not be treated as a verified continuous-current rating.
- Check the PCB terminal labels and wiring configuration before connecting power.
- The module does not provide motor direction reversal by itself.
