Each channel has an AI pin to which you can connect a current

signal. The NI 9208E also has 17 Vsup pins, one for connecting an

external power supply, and one for each channel. There are also

four common pins, COM, that are internally connected to the

isolated ground reference of the module.

The input signals are scanned, amplified, conditioned, and then

sampled by a single 24-bit ADC. The module provides overvoltage

protection for each channel. Only one channel can be in an

overvoltage condition at a time. Refer to the Specifications section

for information about overvoltage protection. Refer to Figure 3 for

an illustration of the input circuitry on the NI 9208E.

You can connect an external power supply to the NI 9208E. This

power supply provides the current for the devices you connect to

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

Vsup pin and the negative lead of the power supply to COM. Install

a 2 A maximum, fast-acting fuse between the external power

supply and the Vsup pin. Refer to the Specifications section for

information about the Vsup pins.

Note The Vsup pins are internally connected to each

other. You can connect only one external voltage supply

to the device.

Caution Do not remove or insert modules if the external

power supply connected to the Vsup and COM pins is

powered on.

You can connect single-ended current signals to the NI 9208E,

including loop-powered and three-wire current transducers. To

connect a loop-powered transducer, connect the current signal to

the AI pin of the channel and the supply terminal to a Vsup pin. For

a three-wire transducer, also connect the common of the device to

COM. Refer to Figures 4 and 5 for illustrations of how to connect

loop-powered and three-wire current transducers to the NI 9208E.

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.
