Optocoupler Isolation Module - 4 Channels

Optocoupler isolation module with 4 channels to optically isolate circuits. This can be used, for example, to switch a high-voltage circuit with a 5V micro-controller.

With the jumper the min/GND of the input and output are connected to each other. Therefore, to get a complete isolation, the jumper must be removed.

Specifications:

• Input voltage (IN1-IN4): 3.6-24V
• Output voltage (V1-V4): 3.6-30V
• Maximum switching frequency: 4kHz
