Caution National Instruments makes no electromagnetic

compatibility (EMC) or CE marking compliance claims

for the NI 9425E. The end-product supplier is responsible

for conformity to any and all compliance requirements.

Caution The NI 9425E must be installed inside a suitable

enclosure prior to use. Hazardous voltages may be present.

Caution Do not operate the NI 9425E in a manner not

specified in these operating instructions. Product misuse

can result in a hazard. You can compromise the safety

protection built into the product if the product is damaged

in any way. If the product is damaged, return it to National

Instruments for repair.

Each channel has a DI pin to which you can connect a digital input

signal. The NI 9425E has four common pins, COM, that are

internally connected to the isolated reference of the module.

The NI 9425E has sinking inputs, meaning that when the device

drives a current or applies a voltage to the DI pin, the pin provides

a path to COM for the current or voltage. The NI 9425E internally

limits current signals connected to DI. For more information about

input current levels, refer to the Specifications section.

You can connect 2-, 3-, and 4-wire sourcing-output devices to

the NI 9425E. A sourcing-output device drives current or applies

voltage to the DI pin. An example of a sourcing-output device is an

open collector PNP.

6|ni.com |NI 9425E Operating Instructions and Specifications

Connect the sourcing-output device to the DI pin on the NI 9425E.

Connect the common of the external device to the COM pin. Refer

to Figure 3 for an illustration of connecting a device to the

NI 9425E.

(Three-Wire Device Shown)

The NI 9425E channel registers as ON when the sourcing-output

device applies a voltage or drives a current that is in the input ON

range to the DI pin. The channel registers as OFF when the device

applies a voltage or drives a current that is in the input OFF range

to the DI pin. If no device is connected to the DI pin, the channel

registers as OFF. Refer to the Specifications section for more

information about the ON and OFF states.

Caution To ensure a grounded connection, use shielded

I/O cables and tie the shield to the chassis ground.

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.
