USB-DIO96H/50 |
|
 No recomendado para nuevos proyectos, considerar el modelo con terminales a tornillo: USB-DIO96H |
|
|
|
|
El USB-DIO9H/50 proporciona 96 bits de corriente alta, nivel lógico de entrada y
salida digitales. El USB-DIO96H tiene toda la funcionalidad del USB-DIO96H, pero más
que una terminal de tornillos, ofrece un conector de 50-pernos que iguala el conector del
PCI-DIO96H, haciéndole más fácil sustituir las tarjetas PCI en sus
aplicaciones. El USB-DIO96H/50 es un USB completamente plug and play y fácil de
utilizar. Obtiene toda la energía requerida del puerto USB, así que no se
requiere ninguna fuente de energía externa.
|
|
|
Su fácil uso, bajo costo, y los conectores, hacen al USB-DIO96H/50
ideal para los usos que requieren el nivel lógico confiable de entrada y salida
digitales.
