ABB Module DSDO120 57160001-AK ABB DSDO120 ASEA BROWN BOVERI DSDO FACTORY SEALED

Product Description:

The analog inputs can be used individually in a lot of different operating modes (even as digital inputs).
The operationg modes are configurable. In order to make sure, that unused input channels have
a defined 0V level, they may be shorted to AGND.In the following, some application examples are shown
for analog sensors.Input currents which exceed the measuring range cause an overflow error message. If the measured value is below the range, an underflow error message is generated.The input impedance is ca. 330 W. 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 open-circuit monitoring begins below ca. 3 mA. The value of the range underflow is stored. If the open-circuit
monitoring is configured, the open-circuit event is displayed by the red LED Ovl. as long as it is present. In the PLC system an error message is stored (FK4, error number 9).
The following figure shows the connection of 2-pole passive- type analog sensors 4...20 mA.
