1 INTRODUCTION The PCI-DIO96 is a 96-bit line digital I/O board. The board provides the 96 bits infour 24-bit groups. Each group provides an 8-bit port A and port B, as well as an8-bit port C that can be split into independent 4-bit port C-HI and a 4-bit port C-LO.See Figure 1-1 below. On power up a...

IMPORTANT NOTE WHENEVER AN 82C55 IS POWERED-ON OR RESET, ALLPINS ARE SET TO HIGH-IMPEDANCE INPUT. FOLLOWINGSTANDARD TTL FUNCTIONALITY, THESE INPUTS WILLTYPI...

Page 24 - UNCONNECTED INPUTS FLOAT; TTL TO SOLID STATE RELAYS

If the board is in output mode, the board has enough power to override thepull-up/down resistor's high signal and drive the line to 0 volts. If the output circuitasserts a high signal, the pull-up resistor guaranties that the line goes to +5 V. Of course, a pull-down resistor accomplishes the same t...

The most convenient way to use solid state relays and a PCI-DIO96 board is to use aSolid State Relay Rack. An SSR Rack is a circuit board with input buffer amplifiersthat are powerful enough to switch the SSRs. The buffer amplifiers and SSRs aresocketed. The standard buffer amplifiers are inverting ...
