2. Soldering the headers Before using your click board , make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 RELAY 2 click 2 3 4. Essential features Relay is an electrical switch used to terminate or establish circuit using a low power signal from a microcontroller. Relay provides complete electrical isolation between the microcontroller and controlled circuits. The LCA717 have optically coupled outputs that use the patented OptoMOS technology. Solid Turn the board upside down so that Turn the board upward again. Make sure state relays enable fast, silent and bounce- the bottom side is facing you upwards. to align the headers so that they are free switching. On this click board, each Place shorter pins of the header into the perpendicular to the board, then solder the relay has a corresponding onboard signal appropriate soldering pads. pins carefully. LED to indicate whether its on or off. 1. Introduction Relay 2 click carries two LCA717 single-pole, 3. Plugging the board in OptoMOS solid state relays and two screw click terminals for connecting the wiring. These Once you have soldered the headers your relays have a load current of 2A, low maximum board is ready to be placed into the desired BOARD on-resistance of just 0.15 Ohms, and a mikroBUS socket. Make sure to align the cut www.mikroe.com blocking Voltage of 30V. They are controlled in the lower-right part of the board with the by the microcontroller through RL1 and RL2 markings on the silkscreen at the mikroBUS pins, which are in place of default mikroBUS socket. If all the pins are aligned RELAY 2 click manual ver 1.00 AN and PWM pins. The board is designed to correctly, push the board all use a 3.3V power supply only. the way into the socket. 01000000802838. Code examples 5.
