NI PXIe-8105 Embedded controller
Product introduction
Precautions when configuring a system Design the system with the following considerations to prevent mis-input from the remote I/O module: (1) During power on and power off Start the data link after turning on the power for the remote I/O module. Turn off power for the remote I/O module after stopping the data link.During momentary power failure of the remote I/O module When momentary power failure occurs with the power (24VDC) supplied to the remote I/O module, mis-input may occur. (a) Cause for mis-input due to a momentary power failure The remote I/O module hardware uses the power after internally converting the module power (24VDC) in to 5VDC. When momentary power failure occurs with the remote I/O module, the following condition occurs: (Time for the 5VDC in the internal remote I/O module to turn off) > (input module on off response time) Therefore, mis-input is caused when a refresh is performed within the time indicated by 1 ) in the diagram below.
