System compatibility

PC-DIO-96/PnP belongs to NI legacy ISA DAQ platform.It works with old ISA industrial PCs,supported by Traditional NI-DAQ driver.The PnP design eliminates manual jumper configuration,widely used for switch signal collection,relay control and parallel peripheral communication for legacy automation and test systems.It is spare part for legacy automation equipment overhaul.

Function

PC-DIO-96/PnP is ISA parallel digital I/O board with Plug and Play function.96 TTL channels are configurable as input or output,supports hardware handshaking for high-speed parallel communication.Onboard 8253 timer provides timing and interrupt function for sensor and actuator control.

Installation

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

Interface

‑100-pin multi I/O connector

‑ISA gold finger edge connector

‑Board status indicator

Feature

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

Diagnostic

Fault phenomenon:DIO channel no response,handshake abnormal,fail to auto allocate resources.Check ISA slot contact,100pin wiring,legacy DAQ driver and PnP configuration.

Product Brief

PC-DIO-96/PnP is NI ISA Plug and Play 96-channel bidirectional TTL digital I/O board,with 82C55 PPI and 8253 timer chip,for legacy ISA PC parallel signal control and old automated test equipment renovation.Mainly used for maintenance and replacement of old automation equipment.ESD protection must be followed during handling.
