4 Channel Opto-Isolated Board

Overview

4 Channel Opto-Isolated Board is a 4 channel opto-isolator board assembly that allows microcontroller and other logic circuits to be interfaced to both input and output signals that require opto-isolation.This board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system. This board electrically isolates a controller from the high-power system by use of an opto-isolator IC. this board to allow a microcontroller control servos or other motors that use a higher voltage than the TTL logic on the (3.3V or 5V) micro, and may cause electromagnetic interferance with our system as the motors turn on and off. This board will isolate the systems, creating a type of electrical noise barrier between devices.

4 Channel Opto-Isolated Board

4 Relay Interfacing Board 5V Isolated Raspberry Pi and Arduino Compatible

Overview

The board has four relays driven by ULN2803 IC and MCT2E IC for isolation purpose. The board works on 5V but the input signal can come directly from Raspberry Pi and Arduino output working 5V to control relays. Each relay can switch varierty of AC or DC high voltage, high current loads working at 110V or 220V AC mains like lights, fans, motors and such. The status of relay is indicated by individual LEDs.
