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.
- Operating voltage 12 VDC
- Current consumption < 80 mA
- Contact capacity 3 A / 30 V
- Sensitivity < 5 mA
- Board dimensions approx. 44 x 18 mm
