Fx2424 PLC

The Fx2424 PLC is Triangle Research's top-of-the-line PLC. Featuring a built-in Ethernet interface, the Fx2424 is readily programmable over the Internet using the highly-acclaimed i-TRiLOGI programming/monitoring software (Read F-seies PLC Reviews by Control Design magazine).


The Fx2424 PLC hosts both a PLC webserver and a Modbus/TCP server and connects readily with i-TRiLOGI, ExcelLink, SCADA, HMI and MS-Excel's web query software as well as other enterprise database softwares. Best of all, you also get a FREE Web HMI to go with this Super PLC!


The Fx2424 is also able to perform machine-to-machine (M2M) communication, send dynamic content to any email address based on specified events, as well as open client connections and communicate with other devices over the Internet.

NOTE: Fx2424 replaces the previous F2424 as it now supports the floating-point math and variables available on i-TRiLOGI version 7. It is 100% backward compatible to F2424 PLCs (Read Fx2424 vs F2424.pdf).

The Fx2424 PLC has 24 digital inputs, 24 digital outputs and 12 analog I/Os built-in and is expandable up to 256 digital I/Os. It is capable of controlling and/or driving up to 3 stepper motors directly with up to 4A per phase @24VDC. Its high speed digital inputs allow up to 3 quadrature encoders which may be connected to provide both position and speed information of moving devices.

With 1 RS232 port and 2 RS485 ports and all of them supporting Modbus ASCII/RTU protocols, the Fx2424 is fully equipped for connectivity to a whole range of peripheral devices. Furthermore, each Fx2424 comes equipped with an IR remote control receiver for contactless data entry, and supports an optional ZigBee wireless radio module - XBee supplied by Digi International Inc.


Just as notable is Triangle Research's proven i-TRiLOGI "Ladder+BASIC" programming software which makes complex programming of the Fx2424 PLC a whole lot easier than with standard ladder-logic programming! By combining the Ladder Logic program with a floating-point math-capable BASIC langugage (i-TRiLOGI version 7), this great controller is packaged to be ready immediately to interface to power meters, HVAC sensors, and/or talk to other other controllers to carry out sophisticated control tasks in a commercial building project.

This highly flexible product is certainly poised for applications in factory, home and building automation. The Fx2424 PLC price-to-performance profile is positioned as much for the mid to high-end OEM machine builder and factory/plant system integrators as it is for the building automation designer. For the user who needs the integrated features and connectivity of a PLC, the Fx2424 is the perfect choice.
