5 Control inputs and outputs

5.1 Analog input EM-S1INA

5.1.1 General

The analog input of the EM-IO-02 expansion module can optionally be confi

ured 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 parameter

Limit Source 734…737).

5.1.2 Configuration voltage/current input

The analog input of the EM-IO-02 expansion module has been configured in the fac-

tory setting for a voltage signal of +/- 10 V.

Switch S3 enables the switch-over of the operation mode for an analo

current si

nal

of +/-20 mA.

Operation mode – switch S3 Function

OFF - Voltage input OFF (to the right) –

analog input EM-S1INA is configured for a

voltage signal.

ON - Current input ON (to the left) –

analog input EM-S1INA is configured for a

current signal.

Note: With the two switches S1 and S2, the bus connection of the system bus

interface is configured (refer to chapter "System Bus Interface").
