Compact PLC packs in performance
Mitsubishi Electric has expanded its MELSEC FX3 series of PLCs with the FX3G, a compact controller for mechanical handling and plant engineering automation, offering 128 I/O (which is expandable to 256 I/O with a serial network), a powerful CPU and easy configuration through clip-on application modules.
The FX3G replaces the FX1N, resetting the cost-performance expectation with a larger program memory, faster instruction execution, additional programming instructions and improved functions and expansion options. Advances have been made in communication and positioning functions, and the seamless integration of other control devices and networking options.
In addition to the standard system bus for up to eight expansion, special function and network modules, the new controller also has a second bus system like it's bigger brother the FX3U. Up to four additional modules - two interface modules (RS-232 or RS-485) and two analogue adapters, including a new temperature data acquisition module for Pt1000 and Ni1000 elements - can be connected to this "adapter bus", making this compact PLC extremely flexible.
