ABB Module DSQC679 3HAC028357001 ABB DSQC679 3HAC028357001 DSQC 679 For new products
Product Description:
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.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. 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).

Product's Character:
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

In this way the correct measurement will succeed after the current has reached a normal value again.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.
