RobotDyn® 4 Relay Shield Uno Module For Arduino 400mA 6-12V For Motors Pumps

Feature: Compatible with the form factor, Arduino Rev3 4 relays and the control channel LED indication for relay Selecting any of the digital pins D0-D13 to control relays Full decoupling circuits of the controller and relay control via optocouplers Options relay: Load AC-240V / 10A, DC-60V / 10A Current consumption: 6-12V / 400mA We have improved the shield for greater security: 1. We placed the relays and the terminals themselves outside the area of board Arduino 2. We optocoupler (4-channel optocoupler TLP521-4) for isolation the relays from microcontroller, now the Arduino circuit and signal outputs are not switching relay itself. 3. The tracks connecting the relay board and terminals have an additional layer of solder to withstand high loads. For flexibility in the use of I/O of the Arduino, relay control channels can be connected to any D0-D13 Arduino, with jumpers (Wire jumper). It means you are not tied to any I/O. Package includes: 1 x 4 Relay Shield Uno Module
