Keithley's KPCI-3130 Series of Universal Analog Output Source Boards

nnnn

are designed specifically for applications where robust analog output and

nnnn

industrial digital I/O control are required. Whether the application is on

nnnn

the factory floor or in the lab, the KPCI-3130 Series offers precision signal

nnnn

sourcing performance and unmatched quality at an economical price.

nnnn

Both boards lower the cost of automation and meet the needs of large ATE

nnnn

(automated test equipment) and machine automation applications.

nnnn

The KPCI-3130 Series is a family of two value-priced analog output boards

nnnn

for the PCI-bus: the KPCI-3130 and -3132. These boards are ideal for appli-

nnnn

cations requiring multiple analog outputs and control capabilities. Typical

nnnn

applications include semiconductor machine control, product testing, simu-

nnnn

lation testing, and servo control. The KPCI-3130 provides eight channels of

nnnn

industrial grade analog output channels along with 32 high current digital

nnnn

I/O channels designed for controlling solenoids, valves, actuators, or solid

nnnn

state relays. The KPCI-3132 offers two channels of wide resolution analog

nnnn

output that can be used for driving chart recorders, programming power

nnnn

supplies, motor control, or applications where a precise voltage is needed.

nnnn

If your applica-

nnnn

tion requires that a

nnnn

constant current be

nnnn

supplied, the KPCI-

nnnn

3130 Series can be configured to source or sink

nnnn

up to 20mA without an external excitation source.

Functional Description

nnnn

The KPCI-3130 Series of Universal Analog

nnnn

Output Source boards provides a wide resolu-

nnnn

tion using a single ±10V range. With a universal

nnnn

resolution of 19/xV, glitching problems normally

nnnn

encountered when switching to different ranges

nnnn

on conventional multi-range analog output

nnnn

boards are eliminated with a single range. This

nnnn

allows you to concentrate on the application

nnnn

without worrying about the complications range

nnnn

change glitches cause.

nnnn

Most conventional PC-based analog output

nnnn

boards only provide you with a two-wire con-

nnnn

nection as shown in Figure 1. For most applica-

nnnn

tions, this is more than adequate and will meet

nnnn

your application needs. However, when you

nnnn

are required to run a cable over a long distance

nnnn

between the source of the analog output and the

nnnn

point where the analog output voltage must be

nnnn

applied, significant voltage drops can occur as

nnnn

the result of cable resistances, device intercon-

nnnn

nections, and terminations; therefore, the pro-

nnnn

grammed output value may not be the voltage

nnnn

delivered at the point where the voltage is being

nnnn

applied (such as at the DUT [Device Under Test],

nnnn

the device being controlled, etc.).

nnnn

To correct the problem of voltage drops across

nnnn

long lead lengths, the KPCI-3130 Series allows

nnnn

you to connect the outputs in a four-wire remote

nnnn

sensing mode, similar to what is used on conven-

nnnn

tional power supplies. The 4-wire remote sense
