WARNING REGARDING MEDICAL AND CLINICAL USE
OF NATIONAL INSTRUMENTS PRODUCTS
National Instruments products are not designed with components and testing intended to ensure a
level of reliability suitable for use in treatment and diagnosis of humans. Applications of
National Instruments products involving medical or clinical treatment can create a potential for
accidental injury caused by product failure, or by errors on the part of the user or application
designer. Any use or application of National Instruments products for or involving medical or
clinical treatment must be performed by properly trained and qualified medical personnel, and all
traditional medical safeguards, equipment, and procedures that are appropriate in the particular
situation to prevent serious injury or death should always continue to be used when National

Operator's Safety Summary
The general safety information in this summary is for both operating and servicing personnel.
Specific warnings are found throughout the manual where they apply but may not appear in this
summary.
Terms
In this manual, Warning statements identify conditions or practices that could result in personal
injury, loss of life, or damage to equipment or other property.
1. Heed all warnings and safety instructions.
2. Never make any signal or cable connection or disconnection when devices are powered on.
All connections must be made with devices powered off. Failure to do so can result in a
shock hazard.
3. If any voltage potentials can possibly exceed 30 V–particularly potentials across the
optocouplers or relays–the SC-206X Series board must be completely enclosed in order to
protect the operator from shock when devices are powered on. Do not leave the SC-206X
Series boards uncovered under these circumstances.

About This Manual
This manual describes the mechanical and electrical aspects of the SC-206X Series boards and
contains information about installing and operating the boards. The SC-206X Series consists of
three digital signal conditioning boards you can use with National Instruments data acquisition
boards–the SC-2060 optically isolated digital input board, the SC-2061 optically isolated digital
output board, and the SC-2062 electromechanical relay digital output board. You can use the
SC-206X Series boards for digital signal conditioning on the Macintosh NuBus computers with
the NB Series and Lab-NB boards, the IBM Personal System/2 (PS/2) Micro Channel computers
with the MC Series boards, and IBM PC/XT/AT and compatible computers with the AT Series
and Lab-PC+ boards. Each of the SC-206X Series boards is described in detail in this manual.
