Internal RTC
Accuracy
Integrated Voltage Input Monitor
The integrated voltage input monitor underreports the voltage at the power connector by up to
400 mV because of voltage drops across internal circuits.

Power Requirements

You must power the cRIO-9023 using a National Electric Code (NEC) Class
Note
2/UL listed ITS LPS power supply or mount the cRIO-9023 in a suitably-rated metal
enclosure.
Recommended power supply
Power consumption
cRIO-9023 only
cRIO-9023 supplying power to eight
C Series modules
Voltage requirement
On powerup
After powerup
The cRIO-9023 is guaranteed to power up when 9 V is applied to V and C.
Note
After powerup, it can operate on as little as 6 V.

Physical Characteristics

If you need to clean the controller, wipe it with a dry towel.
