The sbRIO-9628 is an embedded CompactRIO Single-Board Controller that integrates a Real-Time processor, a user-reconfigurable FPGA, and digital I/O on a single printed circuit board (PCB). You can embed the sbRIO-9628 in high-volume OEM applications that require flexibility, reliability, and high performance. This controller features two Gigabit Ethernet connectors, two RS-232 serial ports, an RS-485 port, a CAN port, microSDHC, sixteen 16-bit analog inputs, four 16-bit analog outputs, four 5 V tolerant DIO ports, and a high-density RIO Mezzanine Card (RMC) connector that provides the option to connect two C Series I/O modules and 96 2.5 V/3.3 V single-ended digital I/O lines or 45 differential pairs. Regarding the analog inputs you can have 16 single-ended or 8 differential as indicated in the
