ABB Module DO620 3BHT300009R1 ABB DO620 DIGITAL OUPUT USED Performance great

Product Description:

In case of a configured plausibility monitoring, range underflow and range overflow by 2...3 % result in an error message (FK4, error number 10).Independent of the configured monitoring, the error values +32767 and -32767 are always generated in case of range underflow and range overflow. Exception: In the measuring range of 0...20 mA only the range overflow is detected.Input voltages that exceed the measuring range cause the overflow numerical value of +32767. If the measuredvalue is below the range, the underflow numerical value of -32767 is set.Input currents that exceed the measuring range caus 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 hasa 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.

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.
