The new PLC, part of Mitsubishi’s Melsec iQ-F series, uses the same CPU as the FX5U model in a package as small as a micro FX3S. It has a program memory of 128,000 steps and an execution speed of 34ns, resulting in fast machine responses and high productivity. Built-in tools such as security key authentication prevent data theft and tampering, while allowing operators to access system status safely via the Web and to interact with on-board functions such as data-logging.
The tiny CPU can fit into tight spaces, freeing up on-machine or production floorspace. There are 16 digital inputs and 16 relay / transistor outputs, avoiding the need to install additional, space-consuming terminal blocks in many applications. The modules can be unlocked from a rail and moved together with their wires, simplifying maintenance and system change tasks. The use of spring-clamp terminals speeds up wiring, while ensuring reliable, vibration-resistant connections.
Mitsubishi launched its first micro-controllers, the FX family, more than 35 years ago. Since then, around 19 million Melsec-FX controllers have been installed.
