Control characteristic
The control characteristic is established by the maximum value of the dimensions to
be controlled and the key values of the set point. Using these key values, the linear
control characteristic may be set as desired.
Each controller (e.g. temperature controller) whose output signal lies within the
range 0-20mA / 0-5V / 0-10V, can easily be adapted to the Power Controller.

Relay outputs
Change-over contact, contactor material: AgSn02 / Au plated
The relay can be used for weak load circuits ( 5V 20mA),
but not after a prior load with 230V a.c.
Max. values: 250V 6A 180W, 1500VA
Insulation strength 4kV / 8mm
Ambient temperature
35°C external cooling (F model with integrated ventilator)
45°C self air cooling
At higher temperatures it is possible to operate with reduced type current:
Temperature range up to 55°C: type current -2% / °C
