National Instruments NI-9145 CompactRIO Chassis

The National Instruments NI-9145 (Part number: 784756-01) CompactRIO Chassis is a highly durable model for incorporating deterministic, distributed I/O to any CompactRIO, PXI, or industrial controller with dual Ethernet ports. For fast expansion of a real-time system, this Chassis can be configured using Scan Mode. The front panel of the NI-9145 has a FPGA LED which can be used to easily retrieve application statuses or debug applications. The NI-9145 has EtherCAT compatibility, a 100BaseTX Ethernet network interface, 100 m/segment maximum cabling distance, and 100 Mbps communication rates. This model also features a Xilinx Zynq-7000 (Z-7020) FPGA, which can be reconfigured for custom use. The reconfigurable FPGA has 4,480 kbits available block RAM, and 106,400 flip-flops, 85,000 logic cells.

The NI 9145 CompactRIO Chassis additionally has Safe-State Output and Slave Timing Mode features. During normal operation or in cases where a serious error occurs, the NI 9145 passes through the EtherCAT safe state when moving from LabVIEW Active Mode to LabVIEW Configuration Mode. This model uses the EtherCAT distributed clock while operating in a synchronized or free-run mode.

The NI-9145 CompactRIO Chassis supplies up to 20 W, 24 VDC and accepts voltage between 9 V to 30 V. This model features industrial grade specifications with its 50 g shock and 5 grms vibration. The NI-9145 Chassis’ dimensions are 10.74 in. × 3.47 in. × 2.45 in. This model weighs 34.6 oz. The screw-terminal wiring gauge for this model is 0.2 mm 2 to 2.1 mm2 (24 AWG to 14 AWG).
