产品描述
The controller series comprises five freely configurable, universally usable compact controllers
in various DIN formats to control temperature, pressure, and other process variables.
The devices are characterized by a simple, clearly structured operation supported with texts.
Process values and parameters are represented by two 18-segment LCD displays. The types
702112, 702113 and 702114 are additionally equipped with a pixel matrix LCD display for displaying
text. In addition, all devices have individual display elements for the switch positions of
the outputs as well as for manual mode, ramp function, and timer. The devices are operated using
a membrane keyboard with four buttons and can be used under harsh environmental influences
thanks to the high IP65 protection type.
Depending on the hardware design, the devices can be used as two-state controllers, three-state
controllers, three-step controllers, or continuous controllers. The basic type includes autotuning,
a ramp function, a program controller, manual mode, limit value monitoring functions, digital control
signals, extensive timer functions, and a service counter. A math and logic function is also
available as an option. Furthermore, the user has the option to create his/her own application
using structured text (ST code).
The devices can be conveniently configured using a PC 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).
