Description Boardoza PC817C 2CH Isolated Level Shifter is a dual-channel signal level isolation and conversion module based on the Sharp PC817C optocoupler. Each channel provides galvanic isolation between the input and output sides, helping protect circuits and transmit signals safely between different voltage domains. The board supports 3.3V to 12V on both input and output sides, making it suitable for microcontrollers, sensors, PLC interfacing, industrial control, and noise-sensitive signal conversion. Features Two independent optically isolated channels Based on the Sharp PC817C optocoupler Supports 3.3V - 12V input and output signal levels Unidirectional signal transmission for logic level shifting Optical isolation helps reduce electrical noise and interference Compact 20mm x 40mm breakout board Suitable for control, automation, and microcontroller interfacing Specifications Specification Parameter Model Sharp PC817C Manufacturer Sharp Corporation Function Isolated level shifting Number of Channels 2 Input Voltage Range 3.3V - 12V Input Current, per Channel ≤ 60 mA Output Voltage Range 3.3V - 12V Output Current, per Channel ≤ 50 mA Maximum Operating Frequency 1.5 kHz Duty Cycle Variation +/-5% max Operating Temperature -55°C ~ +110°C Board Dimensions 20mm x 40mm Dimensions Interface Connector Pin Description J1 Power Supply Connector VIN Voltage supply for output signal level J1 Power Supply Connector GND Reference ground for output side J2 Input Channel 1 IN1+ External signal input for Channel 1 J2 Input Channel 1 IN1- Return ground for Channel 1 input J3 Input Channel 2 IN2+ External signal input for Channel 2 J3 Input Channel 2 IN2- Return ground for Channel 2 input J4 Output Channel 1 OUT1 Converted signal output for Channel 1 J4 Output Channel 1 GND Output reference ground for Channel 1 J5 Output Channel 2 OUT2 Converted signal output for Channel 2 J5 Output Channel 2 GND Output reference ground for Channel 2 Applications Logic level shifting between different voltage domains Microcontroller and sensor signal isolation Industrial control signal conversion PLC interfacing Noise protection in electronic systems Product List Quantity Item 1 Boardoza PC817C 2CH Isolated Level Shifter Resources Official GitHub Repository PC817C 2H Datasheet PDF Boardoza PC817C 2CH STEP File FAQ How many isolated channels does this board provide?
