Working principle The controller has two four-digit, 7-segment displays for process values (red) and setpoints (green). The displays can be used to add comments when you program your inputs. The controller has one analog input for any common transducer type, two relay outputs, two combined binary inputs / logic outputs and one 4-20 mA analog output for controlling actuators.One free slot is provided to allow an additional option, such as a Profibus card, to be retrofitted if required. The controller is also equipped with four limit comparators that can be assigned to the source signals. You can choose between eight different limit comparator functions. One program function with eight program segments and two autotuning (self-optimization) methods (oscillation and step response) are provided as standard.

Key features - Programmable analog input- 2 autotuning methods- Program function with 8 segments or ramp function- 2 timer functions- 4 limit comparators- Key and level inhibit- 4 programmable setpoints, 2 parameter sets- 4-digit resolution (max. 2 decimal places)- Controller structures: P, PD, PI or PID- Process value inputs for all common transducer types (see technical data)- 2 relay outputs 230 V / 3 A (NO)- 2 combinable binary inputs / logic outputs- Analog output 4-20 mA
