Safety
This product is designed to meet the requirements of the following
standards of safety for electrical equipment for measurement, control,
and laboratory use:
• IEC 61010-1, EN 61010-1
• UL 61010-1, CSA 61010-1
Note:
For UL and other safety certifications, refer to the product label or
visit
ni.com/certification,
search by model number or product line, and
click the appropriate link in the Certification column.
The maximum input logic high and output logic high voltages assume a V
CC
supply voltage of 5.0 V.
Given a V
CC
supply voltage of 5.0 V, the absolute maximum voltage rating for each I/O line is -0.5 to
5.5 V with respect to GND.

Electromagnetic Compatibility
This product is designed to meet the requirements of the following
standards of EMC for electrical equipment for measurement, control,
and laboratory use:
• EN 61326 EMC requirements; Minimum Immunity
• EN 55011 Emissions; Group 1, Class A
• CE, C-Tick, ICES, and FCC Part 15 Emissions; Class A
Note:
For EMC compliance, operate this device according to
product documentation.
The total current sinking/sourcing from one port cannot exceed 100 mA.
Power Requirements
Power consumption (typical)............... 375 mA on + 3.3 VDC
No load current ................................... 250 mA on + 5 VDC
With a load, use the following equation to determine the power
consumption on a 5 V rail. In the equation
j
is the number of the channels
you are using to source current.

CE Compliance
This product meets the essential requirements of applicable European
Directives, as amended for CE marking, as follows:
• 2006/95/EC; Low-Voltage Directive (safety)
• 2004/108/EC; Electromagnetic Compatibility Directive (EMC)
Note:
Refer to the Declaration of Conformity (DoC) for this product for
any additional regulatory compliance information. To obtain the DoC for
this product, visit
ni.com/certification,
search by model number or
product line, and click the appropriate link in the Certification column.
Power available at I/O connector....... 1 A (fused), maximum
(combined or individually)
Note:
The voltage at the I/O connector is dependent on the
amount of current drawn from an NI 6509.
