For controlling and monitoring
digital signals with voltages greater than standard 5 V logic levels, the model PIO-HV is a
24-bit parallel interface (for IBM and compatible computers). Interfacing most standard
logic level boards to higher voltages requires external signal conditioning, which is both
expensive and bulky. Electromechanical relays are often used to expand the output
capabilities of some digital output boards, but can give a low switching speed, high power
consumption and relatively short life. Unlike most digital I/O boards designed to interface
directly with +5 V logic signals (such as LSTTL or NMOS families), the PIO-HV offers
high voltage input and output capabilities.
The PIO-HV's 24 bits are divided into three 8-bit ports. Port A is an
8-bit input port and port B is an 8-bit output port; port C is switch selectable for input or
output. With this switch located on the rear panel of the board, a user can easily set the
switch to change port C without opening the computer. The output ports are open collector
and will switch 25 mA at up to 50 Vdc. The input ports will monitor voltages up to 32
Vdc.
A 37-pin D connector, which extends out the rear of the host computer, provides easy
access to all connections. Use of the STA-U screw terminal board simplifies field wiring.
Programming can be accomplished simply by reading and writing to register locations.
Also supported by Labtech Notebook Software for Windows for turnkey operation.
