Self-Tuning Universal Controller
KS 92-1
Description
Voltage / Current
The universal controller is suitable for single closed-loop control systems and for automating industrial processes. The
equipment is highly flexible and an economical and efficient solution for many industrial applications. The controller is self
tuning during start-up and to the setpoint. An optional serial interface RS 422/485 is also available. The configuration
and para­mete­ri­zation data are stored in an EEPROM. The user-friendly three-line alphanumeric “day & night” display
enables convenient menu-driven operation on site of the controller by entering the configuration and parameter
settings in accordance with the existing operating conditions and requirements.
Function Continuous controller
PID controller Proportional band Xp:
1 to 9999 Integral time Ti [s]:
0.1 to 9999 s Derivative time Td [s]:
0.1 to 9999 s Switching controller 2 position (on-off) or 3 position stepping controller
The universal controller KS 92-1 is self optimizing, which means that the equipment itself tunes the optimum control
parameters to the setpoint.
Design Controller case in accordance with DIN 43700 for panel mounting and installation in control cabinets.
Wiring via screw-type terminals on back of housing.
For conductor cross-section from 0.5 to 2.5 mm2.

Note When connecting inductive loads, e. g. control contactors, make sure that the contactors are provided with RC
suppressor circuits according to the specification of the manufacturers of the contactors in order to prevent high
voltage spikes.
