The FX3GE sets new standards

The FX3GE Series is the most versatile compact PLC from Mitsubishi Electric and introduces yet another top model to the FX3 range. In addition to the powerful functions of the FX3G series, the FX3GE also boasts integral analog inputs/outputs and Ethernet connectivity. Other features include an RS422 interface and a USB programming port. The FX3GE therefore sets new class standards for compact PLCs; it provides excellent value for money, and is ideally suited for many applications. Typical fields of use include the foodstuffs industry, processing machines, packaging technology, pumps and refrigeration systems.

More functionality

For processing analog values, the FX3GE comes as standard with two analog inputs and one analog output, each having a resolution of 12 bits (0–4000). The FX3GE also features an Ethernet port with a transmission rate of 100/10 Mbit/s. The Ethernet port is ideal for programming and monitoring and for making online modifications. It also enables the unit to be connected to graphical operating panels (HMI), such as Mitsubishi Electric‘s GOT Series. With this Ethernet port, the FX3GE also provides a facility for monitoring process values using a web browser. The PLC can therefore be maintained and monitored regardless of where the FX3GE is installed. Appropriate access rights can be assigned using different password levels.

Flexible expansion options

FX3GE base units are available with 24 or 40  inputs/outputs and can be easily expanded. The simplest way of expanding the units is by means of digital or analog expansion adapters or communications adapters which can be fitted directly to the controller. These adapters are extremely easy to fit in the base unit and provide a cost-effective means of achieving additional capacity without taking up more space. Almost all expansion units for the FX3G, FX3U und FX2N can be used. Expansion modules can be fitted to the right of the controller, and adapter modules from the FX3U range can be connected to the left of the PLC. Analog signals and signals from temperature sensors can be measured straightforwardly and quickly with the help of these adapter modules.
