with an analog plug-in module 8278IB, because they provide the required
software.
3.7.1 Features
The analog plug-in module 8279IB provides a second analog input. It converts an
analog input signal (0 ... 10 V or 0 ... 20 mA) into a digital signal (pulse frequency
0 ... 10 kHz) with the following levels:
- LOW level = 0 V ... 3 V
- HIGH level = 12 V ... 30 V
For operation with 4 ... 20 mA, the following codes must be parameterised:
- C426 = 125 %
- C427 = -12.5 %
Further notes can be obtained from the code table.
Controllers of the 8210, 8220 and 8240 series equipped with an analog plug-in
module, can be used for the following process controller applications:
- Pressure regulation
- Temperature or volume control
- Setpoint summation
- Speed or dancer-position control
To operate the analog plug-in module, the terminal configuration C007 has to be
set to -28-...-45- or -48- ... -51-.
The inverters with plug-in module are subject to the technical data and application
conditions of the controllers.
