Remote+ Sense +
Remote- Sense -
VAUX Auxiliary power input + (11 V to 28 V)
VAUX_GND Auxiliary power input -
NC No connection
Notice Connect at least 4 Local+ and 4 Local- pins to avoid current overload conditions that could damage the cables or module.
Notice When sourcing power through the IO connector, please connect all VAUX and VAUX_GND pins to avoid current overload conditions that could damage the cables or module.
Notice The module has no safety isolation. Do not attempt to extend output power through cascading channels.
Note A minimum capacitive load of 10 µF is recommended to ensure output stability.
Note NI recommends using the TestScale cabling accessories to connect the 10 total Local+ and 10 total Local- pins for the best transient response behavior and to minimize the voltage drop at the load. Refer to Recommended Cables and Accessories in the TestScale Features manual for a list of available accessories.
