The JUMO controller family has been expanded to include a particularly powerful new product in the form of the JUMO diraTRON. The series comprises five configurable, universally usable compact controllers in various DIN formats to control temperature, pressure, and other process variables. Depending on the hardware design, the devices can be used as two-state controllers, three-state controllers, three-step controllers, or continuous controllers.
The devices are characterized by a simple, clearly structured operation supported with texts. Process values and parameters are shown by two 18-segment LCD displays. Individual models are additionally equipped with a pixel matrix LCD display for displaying text and process information. In addition, all devices have individual display elements for the switch positions of the digital outputs. The basic type includes a ramp function, autotuning, a program controller, limit value monitoring functions, binary functions, extensive timer functions, and a service counter. Four digital control signals enhance the flexibility in the basic type. Furthermore, four configurable math and logic formulas as well as project planning via the programming language ST code (structured text) are available to users for more complex applications and for creating their own applications. Both functions – math and logic – as well as structured text, provide individual flexibility that stretches far beyond the standard configuration.
The devices can be conveniently configured using a PC or laptop with the help of the setup program (incl. program editor and ST editor). No separate voltage supply is required when configuring via the USB interface (USB powered). Furthermore, the setup program has a convenient software tool that monitors and documents the startup, thereby making it much easier. This startup software allows for the visualization and storage of analog and binary signals, even while the plant is being optimized. After all, a visual display of the key process data in real time is essential for control engineers when carrying out demanding processes.
