5.1 Analog input EM-S1INA

5.1.1 General

The analog input of the EM-RES-01 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).

5.1.2 Configuration voltage/current input

The analog input of the EM-RES-01 expansion module has been confi

ured 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.
