【Relay Switch Module】5pcs 1-channel photocoupler isolator with stable performance, triggered by DC 12V and 1mA current.
【Signal Voltage】Positive phase amplification with high-level trigger. Output equals input.
【Level Converter】Opto-isolators can be used as level converters (NPN-PNP, PNP-NPN), signal input to MCU in isolation, or MCU-controlled device output in isolation.
【Control Transformer】Optocoupler isolation board provide isolation between low and high-voltage circuits when used with other electronic devices.
【Functional Application】Devices for microprocessor Input/Output switching, DC/AC power control, communications equipment protection, and power supply regulation.
