REDIS 420 marks the next stage in our production of modern operating terminals, made for technically demanding machines and plants.

A comfortable 15-inch touch-screen and the powerful Intel® Atom ™ 1.1 GHz processor build the basic data of the REDIS 420 and enable to take direct control tasks via Soft-PLC.

Eight foil function buttons with LEDs, 16 digital inputs and outputs (optional) as well as various industrial and network interfaces complete the performance package.

As with all products of the REDIS line, the object-oriented configuration is realized with our software VISU4WINners, which can be operated simply and intuitively.
