Connecting an External Power Supply

You must connect an external power supply with a 9 V DC to
30 V DC voltage range to the NI 9266. This power supply
provides the current for the devices you connect to the module.
You can connect only one external voltage supply to the NI 9266.
1. Connect the positive lead of the power supply to V

sup

.

2. Connect the negative lead of the power supply to COM.

Caution

Do not remove or insert modules if the

external power supply connected to the V

sup

and COM

pins is powered on.

NI 9266 Connection Guidelines

•

Make sure that devices you connect to the NI 9266 are
compatible with the module specifications.

•

You must use 2-wire ferrules to create a secure connection
when connecting more than one wire to a single terminal on
the NI 9266.
