Features: 817 optocoupler drive terminals signal voltages: 3.6-24V. Output terminals voltages ranges: 3.6-30V (output current depends on the specific situation but the maximums do not exceed 10MA, the total power is constant, the voltages and current is inversely proportional) The 817 8/4/2 channel optocoupler isolation board enables secure voltages conversion (3.6-24V) with photoelectric isolation, protecting sensitive circuits from high voltages interferences through independent channel controls and jumpers caps configurations. Featuring compactly design with 8/4/2 isolated channel, individual power indicators, and configurable input or output terminals, this voltages converters module offers 10mA driving capacity and IIC compatibility for flexible system integration. Ideal for electronics engineers, industrial automation designers, and DIY enthusiasts working with PLC systems, motor controls, or sensors interfacs requiring voltages level matching and signal isolation. Perfect for isolating motors drive in robotics, adapting 24V PLC inputs to 5V microcontrollers, or safely monitoring 12V sensors outputs in automotive diagnostic equipment through photoelectric separation. It can realize 3.3 V or 5V to control the interfaces of 3.6-30V voltages.
