WARNING

When using the STA-3108A1, the maximum voltage allowed is 30V RMS, 42.4V peak, or 60VDC. Ex-
ceeding this limit could cause an insulation failure and shock hazard. 

CAUTION

Although the STA-3108A1 is rated for 60 volts peak-to-peak, the board to which it is connected may be
rated for a much lower voltage. For example, the KPCI-3108 analog inputs can only tolerate 35 volts
peak without damage, and digital I/O will be damaged by voltages above +5V.

Specifications

Voltage: 30V RMS, 42.4V peak, or 60VDC
Current: 1 amp maximum
Environment: –30˚C to +85˚C

Safety precautions

Observe the following safety precautions before using this product and any associated instrumentation. Although some instru-
ments 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 the operating information carefully before using the product.

General definitions

The types of product users are:

Responsible body is the individual or group responsible for the use and maintenance of equipment, and for ensuring that oper-
ators 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, 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.

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.

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 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.
