4 Relay Module
with LEDs
(Fully Assembled PCB)
Product Use
This 5 VDC Relay Module is especially developed for Automotive or Hobby use, allowing microcontroller to switch on any high current load.
Command Signal of low current at low voltage (Typically 0.5 milliAmpere @ 3.3 V DC) into the Relay Module electronically switches ON a Higher current Load (up to 10A) at typical automotive system voltage (10 VDC to 14.4 VDC).
In constant ON applications it can carry up to 10 Ampere load.
The 5 VDC Relay Module can be used to switch on AC loads up to 250 VAC, such as lights, fans, motors and other devices ON/OFF while keeping them isolated from the microcontroller.
The LEDs located on the PCB are ON when any corresponding Input Pin (#2 to #5) is connected to Ground Common with Vcc.
Control Input can be connected directly to any output pin of PARALLAX PROPELLER microcontroller without need for any resistors.
The 5 VDC Relay Module is also Arduino Compatible.
