National Instruments 784774-01 8-slot CompactRIO controller

The part number 784774-01 from National Instruments is the identifying part number for the cRIO-9035 8-slot CompactRIO controller.  This controller Intel Atom E3825 CPU with 2 cores, 1.33 GHz CPU frequency, and a cache memory of 1 MB (Shared). This controller supports the NI Linux Real-Time (64-bit) operating system and requires LabVIEW 2014 SP1 or later, LabVIEW Real-Time Module 2014 SP1 or later, LabVIEW FPGA Module 2014 SP1 or later, Eclipse Edition 2014 or later, and NI CompactRIO and Drivers February 2015 or later to run the controller. 

The 784774-01 8-slot CompactRIO controller features 2 EtherNet/IP ports for network capability and supports the 10Base-T, 100Base-TX, and 1000Base-T Ethernet interface. It also supports the IEEE 802.3 protocol standard for Media Access Control. The controller offers communication speeds of 10 Mb/s, 100 Mb/s, and 1,000 Mb/s auto-negotiated. The maximum cabling distance rated for the controller is 100 m/segment. 

This controller also features an RS-232 port with a baud rate of 115,200 b/s. It has 5, 6, 7, and 8 data bits with 1,2 stop bits. The controller has Odd, even, mark, and space parity and uses RTS/CTS, XON/XOFF, and DTR/DSR for data flow control. The RI wake maximum low level is 0.8 Volts, while the RI wake minimum high level is 2.4 Volts. The RI overvoltage tolerance is ±24 Volts. The RS-485/422 (DTE) Serial Port in this controller has a baud rate of 115,200 b/s with XON/XOFF for flow control. 

This module requires 100 Watts of power at 24 Volts DC to operate and consumes 3.4 watts of power in stand-by mode. The controller when unloaded has dimensions of 328.8 mm × 88.1 mm × 109.2 mm and weighs 2,250 g (4 lb 15 oz). The screw terminal wiring has a wiring gauge of 0.5 mm2 to 2.1 mm2 (20 AWG to 14 AWG) copper conductor wire. The controller has an ambient temperature rating of -20 °C to 55 °C with an operating humidity rating of 10% RH to 90% RH, non-condensing. The controller comes with an IP20 rating protecting against dust and scratches but not moisture.
