Analog Modules in IP65
4.1.1
Power Supply of Analog Modules in IP65
The analog module is attached to the AS-interface by using the electromechanical
interface EMS or the expanded electromechanical interface EEMS.
4.1.1.1
Supplying the Sensors/Actuators by AS-Interface
If the voltage supply of the sensors which are to be attached shall be maintained
by AS-Interface, please use the AS-Interface substructure module (article no.
1180) to connect 2 AS-Interface flat cables, respectively the AS-Interface sub-
structure module (article no. 1182) to connect round cables.
4.1.1.2
Supplying the Sensors/Actuators by external Help Voltage 24 V
If the sum of energy that is needed to supply the sensors/actuators exceeds 90 mA
an additional auxiliary power-transmission line must be attached to the analog
module.
To do so, please use the AS-Interface substructure module (article no. 1181) to
connect 1 AS-Interface flat cable and 1 flat cable for external help voltage, respec-
tively the AS-Interface substructure module (article no. 1183) to connect 1 AS-In-
Analog modules offer the possibilities to supply the attached sen-
sors/actuators either via AS
-
Interface or via external help voltage
24 V. The choice is made with the jumpers inside the module. The
substructure module has to be selected according to the variant of
power supply connection - supply by AS
-
Interface or external help
voltage by 24 V - that is chosen.
If sensors/actuators are supplied by AS-Interface, the sum must not
exceed 90 mA.
The AS-Interface Pt100 module can only be powered by
AS-Interface.
