Description

Technical Data

The dual function controller EDR_MIC e.g. for humidity and
temperature consists of two integrated, digital microprocessor controllers and also, optional, an integrated 15VDC power supply for the sensors.

Humidity temperature sensors with the standard signals
0/4...20mA, 0/0.2 ...1V or others are used as readings recorders. In the Galltec+Mela programme you will find a
large selection of different sensors.
The humidity and temperature values are displayed digitally as actual values on the EDR_MIC controller.
The measurement ranges can be set to any scale within
the maximum ranges.
The filters on the controller inputs filter out changes in the
input signal which are too fast. The filter time constant can
be set to between 0.0 ... 100.0 sec by pressing a button.
Thus the control is no longer affected by distortions and
transients.
The individual microprocessor controllers can be programmed independently of each other for the various control tasks. Whether as a two point controller, three point
controller, with timer or ramp function - you decide through
programming. The structure of the controller, e.g. as a PI
controller or PID controller with the corresponding parameters, is also entered via the programming level. Thus a
universal combination controller is at your disposal.
