HP 3488A Switch Control Unit

Der HP 3488A ist eine durch den HP-IP Bus gesteuerte Schalteinheit. Das Gerät mehrere Karteneinschübe, diese sind bestückt beispielsweise mit den verschiedensten Formen von Relais. Mit diesem Gerät werden vollautomatische Testabläufe möglich. Dieses mitlerweile günstig auf dem Gebrauchtmarkt erhältliche Gerät ist eine wahrhaft edle Alternative zu all den am Markt befindlichen Serial und RS232 Steuerplatinen mit logischen Ein und Ausgängen.

The Hewlett Packard 3488A is a HP-IP bus controlled switch unit. The device consists of several plug-in relay cards. There are different type of relay cards available as 4*4 matrix relais, general purpose relais, VHF frequency relais and a digital input output card. This device can be controlled by any software with a HP-IP driver and GPIP card, the instrument was designed for automatic controlled test applications as manufactoring.
