System compatibility

PCI-2702C belongs to NI PCI digital I/O platform.It works with standard PCI industrial PC,supported by NI dedicated driver and DLL library,widely used for discrete signal collection,relay and actuator control in legacy industrial automation and test systems.It is spare part for legacy automation equipment overhaul.

Function

PCI-2702C is non-isolated high-density digital I/O board.Total 128 I/O points,64 Schmitt trigger inputs can latch all channels simultaneously via external strobe signal.64 open-collector outputs drive external loads.Built-in timer and handshake circuit enable synchronous I/O communication with peripheral equipment.

Installation

Insert PCI-2702C into computer PCI slot and fasten bracket.Connect signal wiring to SCSI terminal adapter.Install NI device driver.Take ESD protection before installation.

Interface

‑SCSI high density multi I/O connector

‑PCI gold finger edge connector

‑Board status indicator

Feature

PCI-2702C classic NI high-density digital I/O board.Typical faults:SCSI connector pin oxidation,input/output channel damage,timer circuit failure.Inspect edge connector and channel status before replacement.

Diagnostic

Fault phenomenon:DI/DO channel no response,handshake failure,interrupt abnormal.Check PCI slot contact,SCSI cable wiring,NI driver and strobe signal configuration.

Product Brief

PCI-2702C is NI PCI bus 128-point TTL digital I/O board with 64 Schmitt DI and 64 open-collector DO,hardware handshake and interval timer,for legacy industrial switch signal detection,relay control and old automation equipment renovation.Mainly used for maintenance and replacement of old automation equipment.ESD protection must be followed during handling.
