The CIO-PDISO8 board is a low cost, low profile way to control and monitor high voltage ac or dc directly from your personal computer. It provides 8 electro-mechanical relays for output actuation and 8 isolated digital inputs.
The 8 relays are addressed as a single 8-bit port. Five relays are form C SPDT, while the other three are form A normally open. Each relay is rated to 3 A at 120 Vac or 28 Vdc resistive. The 8 isolated inputs are also addressed as a single byte. The inputs are not polarity sensitive and may be mixed between ac (50 to 1000 Hz) and dc.
Because of the isolation provided on the CIO-PDISO8, no screw terminal or accessory board is required. Cable may be directly wired to the card. For convenience, the optional CIO-MINI37 terminal board provides screw termination.
Outputs
Five form C and three form A relays provide output control for up to 28 Vdc or ac (50-1000 Hz).
Form C relays (SPDT) have 3 contacts (Normally Open, Common, Normally Closed).
The center contact (common) may make contact with either of the other two.
Form A relays have 2 contacts, Normally Open and Common.
Isolated Inputs
Eight opto-isolated inputs provide 500 V of isolation. Each input has a filter which should
be used when monitoring ac signals, and may be used to slow down dc signals.
I/O Map and Programming
Programming a digital I/O board is easy from any language. A base address switch
assigns a unique address to the board's I/O registers. Programming is accomplished by
reading the I/O registers.
Optional software drivers, called UNIV-DRVR, are available for programming in both
DOS, Windows 3.1 & Windows 95. DOS support includes QuickBasic 4.5, Visual
Basic, Turbo C, Visual C++, Microsoft C and Quick C. Windows support includes
Microsoft C, Visual C++, Visual Basic, Borland C, and C++. Labview drivers are also
available. (requires UNIV-DRVR)
