Spanish term or phrase:tarjeta de entrada (especificaciones mecánicas)
Contexto: Todos los sensores irán alimentados a –24 V DC desde la tarjeta de entrada. No se admitirán sondas de vibración, desplazamiento axial o acelerómetros que trabajen con otras tensiones o polaridades.
"Entrada" se puede traducir de muchas formas distintas: input, inlet, entry, etc. Creo que en este caso sería input card, pero quisiera confirmarlo. Muchas gracias.
Power is supplied to the left side of both of the switches. When the switches are open there is no voltage passed to the input card. If either of the switches are closed power will be supplied to the input card.
In _See An AC Input Card and Ladder Logic_ we can start following the circuit (loop) at the power supply. The path goes through the switches, through the input card, and back to the power supply where it flows back through to the start. In a full PLC implementation there will be many circuits that must each be complete.
