Can the cRIO Controller Handle DC Voltage Fluctuation?Hardware: CompactRIO>>Controllers>>cRIO-9002
Problem: I am powering a CompactRIO from a battery. Can the cRIO controllers handle the fluctuations that might occur on the DC supply? Solution: The cRIO Controllers are stable as long as the input is within the recommended range for the specific controller you are using. The recommended range given is the required startup voltage, once the cRIO is running, the required voltage is usually a little lower. Keep in mind that some controllers have different voltage requirements. The controllers are able to handle fluctuation as long as the voltage stays within the recommended range. Controllers have even been known to handle a sinewave with peak-to-peak voltages within the recommended range as an input without issues, although this is not a recommended practice. CompactRIO 900x and 901x controllers are rated from 9-30VDC for start-up operation, and 6-30VDC to maintain operation. A single 12Volt battery would be sufficient to power these controllers. CompactRIO 907x and sbRIO controllers are rated for 19-30VDC for operation. Two 12V batteries in series or a 24V battery would be required to power these controllers. Refer to the Product Manuals below for specific information on the power requirements of your system.
