4 Relay Shield Uno Module 400mA 6-12V For Motors Pumps RobotDyn for Arduino - products that work with official Arduino b

Feature Compatible with the form factor Rev34 relays and the control channelLED indication for relaySelecting any of the digital pins D0 D13 to control relaysFull decoupling circuits of the controller and relay control via optocouplersOptions relay Load AC 240V 10A DC 60V 10ACurrent 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 board2 We optocoupler 4 channel optocoupler TLP521 4 for isolation the relays from microcontroller now thecircuit 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 relay control channels can be connected to anyD0 D13 with jumpers Wire jumper It means you are not tied to any I O Package includes 1 x 4 Relay Shield Uno Module
