• 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 -MD150T – 27.10.2014 – v.1.3 page 3... -
Page 4: Device Description
The measurement result is presented on six position display. MD150T has multipurpose usage as well at industry as in laboratory, where averaged or precise force (weight) measurement is necessary. Depends on used sensor there is a possibility of small masses in range as well small weights (grams) as large loads (tons). -

12-36 VDC power supply, min. 250mA Power supply mass Force sensor connection MD150T digital processing unit can be integrated with any force sensor, which has input with resistance of standard bridge bigger than 150Ω. Sensor should be connect according to scheme below. - Page 6 White Yellow Green Tab. 1 Description of cable colors for force sensors of WObit’s offer. CAUTION! In longer period of time can happen, that derivation colors can change. Wrong connection do not cause damage device or sensor. It only cause indicating of opposite value (at changing E+ form E- or S+ from S- derivation), or incorrect (exchange between power supply and output).
