Product Details:

NATIONAL INSTRUMENTS cFP-2120 is a high-performance Compact FieldPoint embedded real-time controller with 200 MHz Pentium-class Vega processor, running LabVIEW Real-Time operating system for autonomous distributed industrial measurement and control. It is equipped with 128 MB SDRAM and 128 MB nonvolatile flash memory, integrated 10/100 Mbps auto-negotiation Ethernet port, three RS-232 ports and one RS-485/422 port, also equipped with CompactFlash slot for removable data storage and program backup. It supports all cFP series I/O modules including analog input, analog output, digital I/O and thermocouple modules. The operating temperature range is -40℃ to 70℃, suitable for harsh industrial sites. It integrates hardware watchdog and built-in self-diagnosis function, supports built-in web server and FTP server for remote front panel access and file transfer. The power supply range is 11–30 VDC, supports panel mounting and rack mounting. This legacy industrial controller is end-of-life, available stock are refurbished replacement spares for vintage industrial automation systems.

This real-time controller can run standalone LabVIEW RT programs, suitable for multi-serial device communication, complex control algorithms and high-speed continuous data logging. Users can download embedded applications, configure network parameters and I/O mapping through NI MAX. It communicates with upper computer via TCP/IP, and can cooperate with multiple cFP I/O modules to build distributed control nodes. Compared with cFP-2100 and cFP-2110, it adds more serial channels and RS485 interface, convenient for connecting PLC, sensors and serial instruments. It is a programmable RT PAC controller, not a simple communication gateway like cFP-1804 and cFP-1808.

It adopts compact industrial metal housing, powered by external 11–30 VDC power supply. Front panel with RJ45 Ethernet port, multi serial ports, CompactFlash socket and status LED indicators for power, run, fault and network. Hot swap of I/O modules is supported, power off is recommended when replacing the whole controller unit or CompactFlash card. The structure meets industrial shock, vibration and EMC requirements for cabinet and panel installation.

It is widely deployed in factory process control stations, environmental monitoring systems, energy automation racks and legacy Compact FieldPoint distributed control systems requiring multi serial communication, RS485 bus and wide temperature range. Typical application scenarios include multi-bus field control node replacement, old FieldPoint RT controller maintenance and vintage industrial control platform retrofit. Automation integrators select this NI cFP-2120 for its 200MHz Vega CPU,128MB SDRAM 128MB flash,10/100Mbps Ethernet,3 RS232 and 1 RS485 port,CompactFlash slot,-40~70℃ wide temperature.
