4 Control inputs and outputs
4.1 Analog input EM-S1INA
4.1.1 General
The analog input of the EM-RES-02 expansion module can optionally be configured as
a voltage or a current input. Parameterization of the input signal is done by the defini-
tion of a linear characteristic and assignment as a
− reference value source
(can be selected via the parameter
Reference frequency source
475),
− reference percentage source
(can be selected via the parameter
Reference percentage source
476),
− actual percentage source
(can be selected via the parameter
Actual percentage source
478, in configura-
tion x11) or
− limit value sources
(can be selected via the parameters 734…737).
4.1.2 Configuration voltage/current input
The analog input of the EM-RES-02 expansion module has been configured in the
factory setting for a voltage signal of +/- 10 V. Switch S3 enables a switch-over of the
operation mode for an analog current signal of +/-20 mA.
