ABB Module DO630 3BHT300007R1 ABB DO630 DIGITAL OUTPUT Highest version
Product Description:
If the analog current sensors 4...20 mA are powered from a separate power supply unit, the reference
potentials 0V (of the separate power supply unit and the power supply unit for the 07 KT 94) must be interconnected to each other.In the above example, the AGND terminal remains unused.Sensors
4...20 mA Fig. 4-24: Example for the connection of currentsensors 4...20 mA at the analog inputs.Input currents that exceed the measuring range cause the overflow numerical value of +32767. If the measured value is below the range, the underflow numerical value of -32767 is set. The input impedance is ca. 330 Ω. The current input has a self-protecting mechanism. If the input current gets too high, the shunt is switched off and the value for range overflow is generated. About every second, the unit tries
to switch on the shunt again. In this way the correct measurement will succeed after the current has reached a normal value again.

Product's Character:
The trigger of the self-protecting mechanism is displayed by the red LED Ovl as long as the overload is present. In the PLC system an error message is then stored (FK4, error number 4). The following figure shows the connection of a 3-wire sensor powered by 24 V DC and of a 2-pole sensor powered
electrically isolated. Both sensors work as active current sources 0...20 mA. It has to be taken into consideration, that in this application the M terminal of the basic unit 07 KT 94 is the reference potential. AGND1 is not dimensioned for carrying the sum of the sensor currents.
