Current outputs
The function group CURRENT OUTPUT is used to configure the individual outputs. Either a
linear (O3 (1)) or, in conjunction with the Plus packet, a user-defined current output
characteristic (O3 (3)) can be entered. Furthermore, a current output value can be simulated to
check the current outputs (O3 (2)).
Example of a user-defined current output table
Between two table pairs, the distance
∆
signal
per mA
must be greater than:
First enter the required current output configuration in the blank table below. Calculating the
resulting signal distance
per mA
ensures that you keep to the required minimum slope. Then
enter the values in the instrument.
