KPXI-RDI-900-01 Rev. A / January 2007
The following safety precautions should be observed before using this product and any associated instrumentation. Although
some instruments and accessories would normally be used with non-hazardous voltages, there are situations where hazardous
conditions may be present.
This product is intended for use by qualified personnel who recognize shock hazards and are familiar with the safety precautions
required to avoid possible injury. Read and follow all installation, operation, and maintenance information carefully before using
the product. Refer to the manual for complete product specifications.
If the product is used in a manner not specified, the protection provided by the product may be impaired.
The types of product users are:
Responsible body is the individual or group responsible for the use and maintenance of equipment, for ensuring that the
equipment is operated within its specifications and operating limits, and for ensuring that operators are adequately trained.
Operators use the product for its intended function. They must be trained in electrical safety procedures and proper use of the
instrument. They must be protected from electric shock and contact with hazardous live circuits.
Maintenance personnel perform routine procedures on the product to keep it operating properly, for example, setting the line
voltage or replacing consumable materials. Maintenance procedures are described in the manual. The procedures explicitly state
if the operator may perform them. Otherwise, they should be performed only by service personnel.
Safety Precautions
Service personnel are trained to work on live circuits, and perform safe installations and repairs of products. Only properly
trained service personnel may perform installation and service procedures.
Keithley Instruments products are designed for use with electrical signals that are rated Measurement Category I and
Measurement Category II, as described in the International Electrotechnical Commission (IEC) Standard IEC 60664. Most
measurement, control, and data I/O signals are Measurement Category I and must not be directly connected to mains voltage or
to voltage sources with high transient over-voltages. Measurement Category II connections require protection for high transient
over-voltages often associated with local AC mains connections. Assume all measurement, control, and data I/O connections are
for connection to Category I sources unless otherwise marked or described in the Manual.
Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on cable connector jacks or test
fixtures. The American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels greater than
30V RMS, 42.4V peak, or 60VDC are present. A good safety practice is to expect that hazardous voltage is present in any
unknown circuit before measuring.
Operators of this product must be protected from electric shock at all times. The responsible body must ensure that operators
are prevented access and/or insulated from every connection point. In some cases, connections must be exposed to potential
human contact. Product operators in these circumstances must be trained to protect themselves from the risk of electric shock.
If the circuit is capable of operating at or above 1000 volts, no conductive part of the circuit may be exposed.
Do not connect switching cards directly to unlimited power circuits. They are intended to be used with impedance limited sources.
NEVER connect switching cards directly to AC mains. When connecting sources to switching cards, install protective devices to
limit fault current and voltage to the card.
Before operating an instrument, make sure the line cord is connected to a properly grounded power receptacle. Inspect the
connecting cables, test leads, and jumpers for possible wear, cracks, or breaks before each use.
12/06
When installing equipment where access to the main power cord is restricted, such as rack mounting, a separate main input
power disconnect device must be provided, in close proximity to the equipment and within easy reach of the operator.
For maximum safety, do not touch the product, test cables, or any other instruments while power is applied to the circuit under
test. ALWAYS remove power from the entire test system and discharge any capacitors before: connecting or disconnecting
cables or jumpers, installing or removing switching cards, or making internal changes, such as installing or removing jumpers.
Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth) ground.
Always make measurements with dry hands while standing on a dry, insulated surface capable of withstanding the voltage being
measured.
The instrument and accessories must be used in accordance with its specifications and operating instructions or the safety of the
equipment may be impaired.
Do not exceed the maximum signal levels of the instruments and accessories, as defined in the specifications and operating
information, and as shown on the instrument or test fixture panels, or switching card.
When fuses are used in a product, replace with same type and rating for continued protection against fire hazard.
Chassis connections must only be used as shield connections for measuring circuits, NOT as safety earth ground connections.
If you are using a test fixture, keep the lid closed while power is applied to the device under test. Safe operation requires the use
of a lid interlock.
If a screw is present, connect it to safety earth ground using the wire recommended in the user documentation.
!
The symbol on an instrument indicates that the user should refer to the operating instructions located in the manual.
The symbol on an instrument shows that it can source or measure 1000 volts or more, including the combined effect of
normal and common mode voltages. Use standard safety precautions to avoid personal contact with these voltages.
The symbol on an instrument shows that the surface may be hot. Avoid personal contact to prevent burns.
The symbol indicates a connection terminal to the equipment frame.
The WARNING heading in a manual explains dangers that might result in personal injury or death. Always read the associated
information very carefully before performing the indicated procedure.
The CAUTION heading in a manual explains hazards that could damage the instrument. Such damage may invalidate the
warranty.
Instrumentation and accessories shall not be connected to humans.
Before performing any maintenance, disconnect the line cord and all test cables.
To maintain protection from electric shock and fire, replacement components in mains circuits, including the power transformer,
test leads, and input jacks, must be purchased from Keithley Instruments. Standard fuses, with applicable national safety
approvals, may be used if the rating and type are the same. Other components that are not safety related may be purchased
from other suppliers as long as they are equivalent to the original component. (Note that selected parts should be purchased only
through Keithley Instruments to maintain accuracy and functionality of the product.) If you are unsure about the applicability of a
replacement component, call a Keithley Instruments office for information.
To clean an instrument, use a damp cloth or mild, water based cleaner. Clean the exterior of the instrument only. Do not apply
cleaner directly to the instrument or allow liquids to enter or spill on the instrument. Products that consist of a circuit board with
no case or chassis (e.g., data acquisition board for installation into a computer) should never require cleaning if handled
according to instructions. If the board becomes contaminated and operation is affected, the board should be returned to the
factory for proper cleaning/servicing.

Section 1: Introduction KPXI Relay Actuator and Isolated Card User’s Manual
Introduction
Keithley Instruments Model KPXI-RDI-8-16 Relay Actuator and Isolated D/I cards is a digital I/O
card for industrial applications in a PXI system.
The Model KPXI-RDI-8-16 provides 8 relay actuators and 16 opto-isolated digital inputs; all relays
are Form C. They well suited for constant ON/OFF control devices.
All channels are isolated and suitable for collecting digital input signals in a noisy environment. For
identical non-polarized opto-isolated digital input channels, switching can be carried out using ACfiltered or non-AC-filtered channels.
An LED reflects the status of each relay output. When a relay is energized, its corresponding LED
will turn ON, otherwise it is OFF.
The relay outputs and digital inputs are controlled by two bytes of I/O addresses. When a bit is
read or written, its output status will be controlled, or its input status will be monitored. The I/O
signals are routed through to a 37-pin D-type connector on the module's faceplate.
Safety symbols and terms
The following symbols and terms may be found on the KPXI-Isolated DIO series module or used in
this manual.

Introduction
This section contains information about handling and installing Keithley Instruments’ KIDAQ®
KPXI series cards:
• Handling precautions
• PXI configuration
• Installation
Handling precautions
CAUTION Use care when handling the KIDAQ
When handling, make sure to observe the following guidelines:
• Only handle the card on a grounded anti-static mat.
• Wear an an anti-static wristband that is grounded at the same point as the anti-static mat.
PXI configuration
Plug and play
As a plug and play component, the board requests an interrupt number via its PXI controller. The
system BIOS responds with an interrupt assignment based on the board information and system
parameters. These system parameters are determined by the installed drivers and the hardware
load recognized by the system. If this is the first time a KIDAQ
on your Windows® system, a hardware driver needs to be installed. Refer to
detailed information.
Configuration
Configuration is done on a board-by-board basis for all PCI boards on your system. Configuration
is controlled by the system and software. There are no jumper settings required (or available) for
base address, DMA, and interrupt IRQ.

cards contain electro-static sensitive components that can be easily damaged
by static electricity.

Installation for
The configuration is not static, but is subject to change with every boot of the system as new
boards are added or removed.
Troubleshooting
If your system doesn't boot or if you experience erratic operation with your PCI board in place, it's
likely caused by an interrupt conflict (perhaps the BIOS Setup is incorrectly configured). In
general, the solution, is to consult the BIOS documentation that comes with your system.
Installation
Step 1. Install driver software
Windows will find the new module automatically. If this is the first time a KIDAQ® KPXI series
isolated digital I/O card has been installed, a hardware driver needs to be installed. Use the
following installation procedure as a guide.
2-2 Return to Section Topics KPXI-RDI-900-01 Rev. A / January 2007
KPXI Relay Actuator and Isolated Card User’s Manual Section 2: Installation
NOTE Keithley Instruments controllers are pre-loaded with the necessary drivers.
For Windows XP/2000:
1. Insert the CD shipped with the module. The CD should auto load. From the base menu
install the KDIO-DRVR. This is the hardware driver that recognizes the KPXI series
modules. If the CD does not auto load run, then under x:\KDIO-DRVR\DISK1\, you will find
SETUP.EXE (x is the drive letter of your CDROM). This will also run the install.
2. When you complete driver installation, turn off the system.
Step 2. Inspect module
Keeping the “Handling precautions” information in mind, inspect the module for damage. With the
module placed on a firm flat surface, press down on all socketed IC's to make sure that they are
properly seated.
If the module does not pass the inspection, do not proceed with the installation.
CAUTION Do not apply power to the card if it has been damaged.
The card is now ready for installation.
Step 3. Install module
Remove power from the system and install the KPXI card in an available slot.
The PXI connectors are rigid and require careful handling when inserted and removed. Improper
handling of modules can easily damage the backplane.
To insert the module into a PXI chassis, use the following procedure as a guide:
1. Turn off the system.
2. Align the module's edge with the card guide in the PXI chassis.
3. Slide the module into the chassis until resistance is felt from the PXI connector.
4. Push the ejector upwards and fully insert the module into the chassis. Once inserted, a
"click" can be heard from the ejector latch.
5. Tighten the screw on the front panel.
6. Turn on the system.
To remove a module from a PXI chassis, use the following procedure as a guide:
1. Turn off the system.
2. Loosen the screw on the front panel.
3. Push the ejector downwards and carefully remove the module from the chassis.

Step 4. Verify installation
When the system is turned on for the first time with a new module present (or a module in a new
slot), Windows Add New Hardware Wizard attempts to locate the correct driver. If it cannot find
the correct driver, even after you have loaded the driver above in Step 1, then force the Add New
Hardware Wizard to look in Windows system32 directory. The driver files should be in this
location. If they are not, shutdown the system, remove the module, and restart the installation
process.
When the Add New Hardware Wizard finishes, the window will verify whether or not installation
was successful. To confirm if the module is installed correctly at a later time, use Windows Device
Manager. In the Device Manager under KIDAQ Boards, look for a device name matching the
model number of the newly installed board (see
installation is complete. If the board appears with a exclamation point or warning in Device
Manager, the installation was unsuccessful. If unsuccessful, use Device Manager to update the

Form C type relays have three contacts: NC (Normal Close), NO (Normal Open), and COM
(Common). The COM post, located at the middle, must make contact with either the NO post or
NC post. When the control bit is high (1), there is contact between the COM post and NO post. If
the control bit is low (0), there is contact between the COM post and NC post.
In normal power-up and reset, the relay is in low status.
