This document describes how to use the National Instruments 9265E

and includes dimensions, terminal assignments, and specifications for

the NI 9265E. Visit ni.com/info and enter rdsoftwareversion

to determine which software you need for the modules you are 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.

Caution National Instruments makes no electromagnetic

compatibility (EMC) or CE marking compliance claims

for the NI 9265E. The end-product supplier is responsible

for conformity to any and all compliance requirements.

Caution The NI 9265E must be installed inside a suitable

enclosure prior to use. Hazardous voltages may be present.

Connecting the NI 9265E

The NI 9265E has a 10-terminal, detachable screw-terminal

connector that provides connections for 4 analog output channels.

Power Supply COM

The NI 9265E has four analog output channels, AO. Each channel

has a common terminal, COM, that is internally connected to the

isolated ground reference of the module. The NI 9265E also has a

terminal for an external power supply, Vsup, and an external power

supply common terminal, Power Supply COM.

Each AO channel has a digital-to-analog converter (DAC) that

produces a current signal. Each channel also has overvoltage and

short-circuit protection. Refer to the Specifications section for

more information about the overvoltage and short-circuit

protection. Refer to Figure 3 for an illustration of the output

circuitry for one channel of the NI 9265E.

You can connect a load to each channel of the NI 9265E. Connect

the positive lead of the load to the AO terminal. Connect the ground

of the load to the corresponding COM terminal. Refer to Figure 3

for an illustration of how to connect a load to the NI 9265E.

Figure 3. Connecting a Load to the NI 9265E

You must connect an external power supply to the NI 9265E. This

power supply provides the current for the devices you connect to

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

supply terminal, Vsup, and the negative lead of the power supply to

Power Supply COM.

Note You must use 2-wire ferrules to create a secure

connection when connecting more than one wire to a

single terminal on the NI 9265E.

When the module powers on, the channels output the startup

current. Refer to the Specifications section for more information

about startup current. Refer to the software help for information

about configuring startup output states in software. Visit

ni.com/info and enter cseriesdoc for information about

C Series documentation.

Sleep Mode

This module supports a low-power sleep mode. Support for sleep

mode at the system level depends on the chassis that the module is

plugged into. Refer to the chassis manual for information about

support for sleep mode. If the chassis supports sleep mode, refer to

the software help for information about enabling sleep mode. Visit

ni.com/info and enter cseriesdoc for information about

C Series documentation.

Typically, when a system is in sleep mode, you cannot

communicate with the modules. In sleep mode, the system

consumes minimal power and may dissipate less heat than it does

in normal mode. Refer to the Specifications section for more

information about power consumption and thermal dissipation.
