Excellent solution for Industrial automation Discrete I/O development

In addition to the easily toggled relays capable of supporting PNP or NPN lswitching, the ability of the PDISO8 inputs to accept the standard +24VDC signals output by PLC's, Robot controllers, and other industrial automation equipment, makes this a powerful hardware tool while developing software for Industrial safety systems.

First locate the pinout of the 40 pin connector in the PDF user manual (the PDF is available on the MCCDAQ physical CD and on our website). Then use an ohm meter to test both positions of each of the 8 relays, looking for either open or dead-short, depending on the state you are selecting in your software. One lead of the meter would be tied to the relay’s ‘common” pin, while the other would connect to either the Normally Closed or “Normally Open”.

First, make sure you provide proper external power to this board. The main (low level) driver used by the USB-PDISO8 series is the Microsoft HID driver that comes with Windows. If the LED stays off, or just blinks, then try a different USB 2.0 port, or a different PC. If the USB LED on this board turns on solid, then the HID driver has detected this board. If the USB LED goes on solid, then the next step is to install our InstaCal driver (a free download).
