National Instruments cRIO-9805 Ethernet Switch Expansion Module

The cRIO-9805 (part number: 786993-01) is an Ethernet Expansion Module for CompactRIO from National Instruments. The module comes equipped with 4 internally switched ports and a PTP of IEEE 802.1AS. The power supply of the cRIO-9805 has a voltage of 9 V to 30 V, with a max power consumption of 5 W. The CompactRIO system from National Instruments employs additional ports that are capable of 802.1AS network synchronization to carry out a range of control and measurement operations for industrial control and automation systems. 

National Instruments CompactRIO Ethernet Expansion modules are frequently used in situations where it is essential to send data to and from the system through a network. Ethernet extension modules are utilized to connect CompactRIO systems to a LAN or the internet, as well as with other hardware or devices. The cRIO-9805 supports a DHCP + Link-Local Network IP configuration as well as TCP/IP and UDP network protocols. The ethernet communication rates of the module are auto negotiated, and measure 10 (Base-T), 100 (Base-TX), or 1000 (Base-TX) Mbps. When it comes to the timing and synchronization features of the cRIO-9805 Ethernet Expansion Module, the IEEE 802.1AS protocol is over a full duplex 1000 Base-TX. The cabling distance is, at maximum, 100 m/segment. 

The cRIO-9805 is able to be mounted with either a panel mounting kit or a DIN rail mounting kit. Additional accessories that are optional for the module include the CAT-5E Ethernet cables / cable assemblies (available in 0.3M, 1M, 2M, 5M, or 10M). The dimensions of the cRIO-9805 are 1.18 in. × 3.47 in. × 4.21 in, and it weighs 14.3 oz.
