2 Description
Inputs/outputs In addition to the main input (pH/redox) and the secondary input (temperature
compensation), the basic device alone has two binary inputs, two relays, one
voltage supply for external sensors and a setup interface.
Input signals can be shown as numbers or as a bar graph on the graphic
display. Parameters are displayed in plain text for easily comprehensible and
reliable operation.
Optional Three further slots can be fitted with extensive additional configurable inputs
and outputs and interfaces.
Application The device is suitable, for example, for displaying, measuring and controlling:
- pH value and/or redox potential.
- Free chlorine, chlorine dioxide, ozone, hydrogen peroxide and peracetic
acid, in combination with sensors as per data sheet 202630.
- (Hydrostatic) liquid levels with 2-wire transmitters (level probes) as per data
sheet 402090 or data sheet 404390.
- Flow rate in conjunction with transmitters as per data sheet 406010 or
406020.
- Two temperature measuring points.
- Most sensors and transmitters that output standard signals (0 to 10 V or
0(4) to 20 mA).
Because temperature measurement is integrated, temperature compensation
takes place quickly and precisely, which is particularly important for many
analytical measurements.
