This document describes how to use the National Instruments 9475

and includes specifications and pin assignments for the NI 9475.

Visit ni.com/info and enter rdsoftwareversion to determine

which software youneed for the modules youare using. For

information about installing, configuring, and programming the

system, refer to the system documentation. Visit ni.com/info

and enter cseriesdoc for information about C Series

documentation.

Note The safety guidelines and specifications in this

document are specific to the NI 9475. The other

components in the system might not meet the same safety

ratings and specifications. Refer to the documentation for

each component in the system to determine the safety

ratings and specifications for the entire system. Visit

about C Series documentation.

Safety Guidelines

Operate the NI 9475 only as described in these operating

instructions.

Hot Surface This icon denotes that the component may be

hot. Touching this component may result in bodily injury.

Safety Guidelines for Hazardous Locations

The NI 9475 is suitable for use in Class I, Division 2, Groups A, B,

C, D, T4 hazardous locations; Class I, Zone 2, AEx nA IIC T4, and

Ex nA IIC T4 hazardous locations; and nonhazardous locations

only. Follow these guidelines if youare installing the NI 9475 in a

potentially explosive environment. Not following these guidelines

may result in serious injury or death.

Caution Do not disconnect I/O-side wires or connectors

unless power has been switched off or the area is known

to be nonhazardous.

Caution Do not remove modules unless power has been

switched off or the area is known to be nonhazardous.

NI 9475 Operating Instructions and Specifications 4 ni.com

Caution Substitution of components may impair

suitability for Class I, Division 2.

Caution For Zone 2 applications, install the system

in an enclosure rated to at least IP 54 as defined by

IEC 60529 and EN 60529.

Caution For Zone 2 applications, install a protection

device between the input signal and the NI 9475 input

pin. The device must prevent the input Vsup-to-COM

voltage from exceeding 84 V if there is a transient

overvoltage condition.

Special Conditions for Hazardous Locations Use in Europe

This equipment has been evaluated as Ex nA IIC T4 equipment

under DEMKO Certificate No. 07 ATEX 0626664X. Each module

is marked II 3G and is suitable for use in Zone 2 hazardous

locations. If youare using the NI 9475 in Gas Group IIC hazardous

locations or in ambient temperatures of –40 °C ≤Ta ≤70 °C, you

must use the device in an NI chassis that has been evaluated as

EEx nC IIC T4, Ex nA IIC T4, or Ex nL IIC T4 equipment.

Special Conditions for Marine Applications

Some modules are Lloyd’s Register (LR) Type Approved for

marine applications. To verify Lloyd’s Register certification, visit

ni.com/certification and search for the LR certificate, or

look for the Lloyd’s Register mark on the module.

Caution To meet radio frequency emission requirements

for marine applications, use shielded cables and install

the system in a metal enclosure. Suppression ferrites

must be installed on power supply inputs near power

entries to modules and controllers. Power supply and

module cables must be separated on opposite sides of the

enclosure and must enter and exit through opposing

enclosure walls.

Connecting the NI 9475

The NI 9475 has a 25-pin DSUB connector that provides

connections for eight digital output channels.

Each channel of the NI 9475 has a DO pin to which youcan

connect a device. Each channel also has a COM pin and a Vsuppin.

National Instruments recommends youprovide independent COM

and Vsup wiring for each channel to minimize current flow in the

COM and Vsup wiring. The COM pins are all connected together

internally.

Each channel has an LED that indicates the state of the channel.

When a channel LED is lit, the channel is on. When the LED is

dark, the channel is off.

Yo umust connect an external power supply to the NI 9475. This

power supply provides the current for the devices youconnect to

the module. Connect the positive lead of the power supply to Vsup

and the negative lead of the power supply to COM. Refer to the

Specifications section for information about the power supply

voltage range.

Caution Do not remove or insert modules if the external

power supply connected to the Vsupand COM pins is

powered on.

The NI 9475 has current sourcing outputs, meaning the DO pin is

driven to Vsupwhen the channel is turned on.

NI 9475 Operating Instructions and Specifications 8 ni.com

Yo ucan directly connect the NI 9475 to a variety of industrial

devices such as solenoids, motors, actuators, relays, and lamps.

Make sure the devices youconnect to the NI 9475 are compatible

with the output specifications of the module. Refer to the

Specifications section for more information about the output

specifications.

Connect the device to DO and connect the common of the device

to COM. Refer to Figure 2 for an illustration of how to connect a

device to the NI 9475.

Increasing Current Drive

Each channel has a continuous output current of 1 A. If youwant

to increase the output current to a device, youcan connect any

number of channels together in parallel. For example, if youwant

to drive 4 A of current, connect DO<0..3> in parallel as shown

in Figure 3. Youmust turn all parallel channels on and off

simultaneously so that the current on any single channel cannot

exceed the 1 A rating.

I/O Protection

The NI 9475 is short-circuit proof in accordance with IEC 1131-2

and provides overcurrent protection.

Understanding Short-Circuit-Proof Devices

Each channel on the NI 9475 has circuitry that protects it from

current surges resulting from short circuits. Whether the module

suffers damage from these overcurrent conditions depends on the

following factors:

• The amount of current through the channel

• The amount of time the current is above the current limit

• The frequency of the current surges

When the amount of current through the DO pin is greater than

13 A, the channel trips and goes into an overcurrent state. In an

overcurrent state, the channel turns off and the module is not

damaged. If the current through DO is between 6 A and 13 A, the

state of the channel is indeterminate and depends on factors such

as the current level, the temperature, and the power supply.
