This relay card could be released with weak signals from approx. 5 mA upwards and will then switch a relay with a heavy current contact of 3 Ampere. Contact 1 x ON. Ideal as switching amplifier for other kits, which have solely a light emitting diode as output and should switch other devices and machines through the relay contact.
Technical data:
- Operating voltage: 12V=
- Current consumption: < 80 mA
- Contact capacity: 3 A / 30 V
- Sensitivity: < 5 mA
- Board dimensions: approx. 44 x 18 mm
