• Avoid routing control (signal) cables in parallel with or in close vicinity of power and supply cables. • Avoid close vicinity of devices generating high level of electromagnetic and/or pulse interference (high power loads, loads with phase or group power regulation). www.wobit.com.pl Manual -MD150A – 27.10.2014 – v.1.2 page 3...
10000 measurement steps for the range of 0-10V. The measurement result is presented on six position display. Apart from measurement output MD150A has 2 relay outputs which can be freely configured for switching on/off at specified thresholds. The device is also equipped with universal digital inputs which can be used for external triggering of measurements and for “pausing”...

0-20mA (e.g. 4-20mA) set 0-20mA mode. 4.2 Configuration of measurement units MD150A process display enables converting the sensor signal into values in measurement units specific for a given sensor. This allows for indication of e.g. measurement value in meter for distance meter, inclination for inclinometer or pressure in bar for pressure sensor.
10V after 1 sec. (100Hz/99 ->”1). 5. Configuration of relay output MD150A indicator has 2 relay outputs PK1 and PK2 which can be switched on/off depending on current measurement value. The following parameters are used for relay outputs configuration: 1.
DIN1 input, i.e. change of the signal status from 0V to +5..+24V. DIN2 input is used for “freezing” of a current measurement on the MD150A indicator display. The last measured value is displayed (blinks) until DIN2 input reaches high status (+5...+24V).
