Welcome to Hellonewworld, almost products are available, feel free to order what you want!
Feature:
1. Four way 817 optocouplers are used to realize signal control and signal isolation control. The isolation voltage can be controlled directly by single chip computer or other IO port devices.
2. The low voltage control can be achieved. The control terminal can be used to control different voltage levels of external MOS transistor or device interface.
3. On board 4-channel 817 is independent: it can achieve different control voltage values at the same time.
Specification:
Guide gate signal voltage: 3.6-24V
Output Port Voltage Port: 3.6-30V
The jumper can reach the exit gate: high potential or pull the exit pad
Product size: 47*37*10mm/1.85*1.45*0.39''
Note:
Please allow 1-3mm differs due to manual measurement.
Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understand.
