The FX3U series is the third generation of this successful family of compact PLCs. The FX3U compact controllers deliver a performance that was formerly the exclusive domain of larger control systems, but in a much more compact package. In addition to digital and analogue I/O, the FX3U provides modules for drive, servo and high speed positioning applications.
With a cycle time of just 65ns, it is over four times faster than the previous generation of PLCs, giving considerably faster scan times and faster response, bring greater than ever precision control to time critical applications. But importantly, despite the integration of new third-generation technology, the MELSEC FX3 controllers are backwardly compatible to their predecessors.
The FX family now includes four independent but fully mutually-compatible product lines: the FX1S covering 10-34 I/O, the FX1N covering 14-132 I/O, the FX3G covering 14-256 I/O and the FX3U/UC covering 16-384 I/O. In each case the base unit can be combined with optional expansion and special function modules to configure a system precisely tailored to the needs of individual applications.
