• Diseñado para Optoacoplamiento • Útil para conectar sistemas digitales a un sistema de alto voltaje o ruidoso • Compatible con doble onda, fase de vapor y soldadura por reflujo IR • Cumple con RoHS
El Circuito Integrado de la Tarjeta de Optoacoplador tiene dos LED y dos fotodiodos incorporados. Esta placa aísla eléctricamente un controlador del sistema de alta potencia mediante el uso de un Circuito Integrado Optoacoplador.
I should have inspected the schematic more closely. Each output (from the opto-coupler IC) is buffered by a transistor in common-emitter configuration with a 10K pull-up resistor. It can't be used to drive a relay or other load. When the input goes high (logical-1), the opto-coupler IC becomes active, grounds the base of the output transistor, which then turns off. The output then goes to logical-1, pulled high by the 10K pull-up. I ended up buying a couple of naked opto-coupler chips, and tossed this breakout board into the parts bin for a future project.
