The CU8871 offers a CFast socket with USB connector in a compact housing for DIN rail
mounting. CFast cards are used in the industrial environment as data memory for process and
control data. The CFast cards are hot-plug capable in the CU8871 and can hence be plugged
and unplugged like removable data storage devices for exchanging data with other PCs during
operation. The USB 3.0 connection offers the highest data transfer rate possible with a CFast
card, but the CFast adapter can also be connected to PCs with a USB 2.0 interface. Power is
also supplied via USB. Status LEDs indicate whether the CU8871 is connected in addition to
indicating data accesses and providing information on the write protection of the inserted
CFast card.
