Projekt Beschreibung

1x LF-Input, conductive, 2-wire
1x Temperature, KTY2K, 2-wire
1x Analog Output, 0-20mA, 2/3-wire
1x Analog Input, 10V/20mA,2/3-wire
1x Impuls-In-/Output, n/p-switch, 2/3-wire can be used also as a Digital-Input

This module contains all IOs for a typical conductivity mesurement with a range of 1 … 4000μS/cm (configurable). It supports the common cell constants of k = 0.01… 1.0 (configurable). An inte-grated temperature input (for KTY81, PT1000 on request) supplies the necessary temperature compensation.

A special impulse input allows the direct adaption of a hall or reed-contact flow and volume sensor from 0.01 up to 250Hz. Addi-tionaly one universal analog input and one output can be used for other analog sensors/actors, both with a range of 0/4 … 20mA.

Futhermore a semiconductor impulse output is present to control e.g. dosing pumps.
