Field Instruments

General

The instrument has 2 analog inputs and 1 binary input. The first analog input is suitable for connecting standard or standardized signals (0 to 10 V or 0/4 to 20 mA), which can be prepared by any transmitter or sensor (such as a 2-wire transmitter). Pt100, Pt1000 or NTC/PTC resistance thermometers (up to 4 k ohms) can be connected to the second analog input. The power supply for a 2-wire transmitter is integrated in the instrument. 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 secure operation. With two optional relay switching contacts, it is possible to implement both simple switching or alarm functions and demanding control tasks with P, PI, PD and PID action. If required, the instrument can also be provided with two freely configurable and scalable analog outputs (0 to 10 V or 0/4 to 20 mA). The instrument is suitable, for example, for displaying, measuring, and controlling:

• free chlorine, hydrogen peroxide, peracetic acid, chlorine dioxide and ozone in combination with sensors as per data sheet 202630
• the pH value or redox potential with 2-wire transmitters as per data sheet 202701
• (hydrostatic) liquid levels with 2-wire transmitters (level and pressure measuring instruments) as per data sheet 402090 or data sheet 404390
• Flow rate in combination with relevant transmitters.
• Two temperature measuring points.
• Most sensors and transmitters that output standard signals (0 to 10 V or 0/4 to 20 mA).

Features

• Display: mg/l, pH, mV, µS/cm, etc. Special visualizations are also possible with the setup program
• Large, backlit LC graphic display
• A choice of display visualizations: large numbers, bar graph or trend display
• Integrated calibration routines: 1-point and 2-point
• Calibration logbook
• IP67 enclosure protection for surface mounting IP65 enclosure protection for switch cabinet mounting
• Selectable languages: German, English, French; additional languages can be loaded later through the setup program
• The setup program1 allows: user-friendly configuration, system documentation, subsequent loading of additional languages
