This 2-channel module converts voltage levels, operating from 3.6V to 24V in and 3.6V to 30V out, making it versatile for various applications. It’s great for connecting a 24V sensor to a 5V or 3.3V device. It’s designed for noisy circuits, providing electrical isolation between channels. Each channel uses a PC817 optocoupler for conversion and has a jumper for optional ground connection. LEDs indicate input status: on for active input, off for high output.
SPECIFICATIONS
- Input voltage 3.6V to 24V
- Output voltage 3.6V to 30V
- Maximum Output (Emitter) Current: 50mA *
- Maximum Frequency: 4KHz
- Rise and Fall Times: 18us
- Channels: 2
Both channels are independent and can be used with different input and output voltages simultaneously - Input Pins:
- IN1 … IN2: +3.6V to 30 V
- G: Ground
- Output Pins:
- V1 … V2: Phototransistor collector pins
- G: Phototransistor emitter pins
* NOTE: Optocouplers have a low output current. The maximum output current of the PC817 is 50 mA. As a result, you cannot connect high-current components (such as motors, etc.) to the optocoupler output directly. You must use a transistor to supply the current of the output draws more than 50mA.
