System compatibility

PC-DIO-96 belongs to NI legacy ISA DAQ platform.It works with old ISA industrial PC,supported by Traditional NI-DAQ driver,widely used for switch signal acquisition,relay control and parallel communication in legacy test and automation systems.It is spare part for legacy automation equipment overhaul.

Function

PC-DIO-96 is old ISA parallel digital I/O board.96 lines can be individually set as input or output,support hardware handshaking for peripheral communication.Onboard timer chip provides timing and interrupt function for sensor and actuator control.

Installation

Insert PC-DIO-96 into computer ISA slot and fasten bracket.Connect 100pin signal cable to terminal block.Install legacy NI-DAQ driver and set jumper or PnP resource.Take ESD protection before installation.

Interface

‑100-pin multi I/O connector

‑ISA gold finger edge connector

‑Board status indicator

Feature

PC-DIO-96 classic NI ISA digital I/O board.Typical faults:gold finger oxidation,port circuit damage,timer chip failure.Inspect edge connector and channel status before replacement.

Diagnostic

Fault phenomenon:DIO channel no response,handshake abnormal,interrupt failure.Check ISA slot contact,100pin wiring,legacy DAQ driver and board hardware configuration.

Product Brief

PC-DIO-96 is NI ISA bus 96-channel bidirectional TTL digital I/O board with 82C55 PPI and onboard timer,for legacy ISA PC parallel signal control,industrial switch input and automated test renovation.Mainly used for maintenance and replacement of old automation equipment.ESD protection must be followed during handling.
