Overview
This section contains illustrations explaining the analog/digital relation for the various input and output measuring ranges.
Input Range +/- 10 V
The following diagram shows the analog/digital relation for the input measuring range +/- 10 V. The voltage value is calculated along the following formula using the digital measurand: Vn = 3200 x Va (for the linear range):
Input Range +/- 5 V
The following diagram shows the analog/digital relation for the input measuring range +/- 5 V. The voltage value is calculated along the following formula using the digital measurand: Vn = 6400 x Va (for the linear range):
Input Range +/- 20 mA
The following diagram shows the analog/digital relation for the input measuring range +/- 20 mA. The current value is calculated along the following formula using the digital measurand: Vn = 1600 x Ia (for the linear range):
Input Range 1 ... 5 V
The following diagram shows the analog/digital relation for the input measuring range 1 ... 5 V. The voltage value is calculated along the following formula using the digital measurand: Vn = 8000 x Va - 8000 (for the linear range):
Input Range 4 ... 20 mA
The following diagram shows the analog/digital relation for the input measuring range 4 ... 20 mA. The current value is calculated along the following formula using the digital measurand: Vn = 2000 x Ia - 8000 (for the linear range). Disabled channels deliver a value of 0.
Output Range +/- 10 V
The following diagram shows the analog/digital relation for the output range +/- 10 V. When the bus is reset, the outputs use the configured parameters. If the module does not have valid parameters, the outputs will go to 0 V resp. 0 mA.The output voltage value is calculated along the following formula using the digital default value:Va = 1/3200 x Vn.
Output Range 0 ... 20 mA
The following diagram shows the analog/digital relation for the output range 0 ... 20 mA. When the bus is reset, the outputs use the configured parameters. If the module does not have valid parameters, the outputs will go to 0 V resp. 0 mA.The output current value is calculated along the following formula using the digital default value:Ia = 1/1600 x Vn.
