To connect more digital inputs (acc. to SK XU1-POS) to the SK 545E frequency inverter, the optional IO extension
SK EBIOE-2 (275900210) is offered. Connection of the analogue inputs ± 10 V to the SK 545E frequency inverters occurs
directly to the terminal block X4 of the SK 545E from size 5 onward.
As an alternative, the ± 10 V analogue inputs can also be connected with terminal blocks X1 + X2 (see TI 275900210) when
an IO extension of type SK EBIOE-2 (275900210) is used.
**
Commercially available external signal converters are necessary if the analogue outputs of the SK 5x5E frequency inverters
are used and signal conversion to 0/4 … 20 mA compatible with SK CU1-MLT-20mA is necessary.
As an alternative, connection could occur to terminal block X2 (see TI 275900210) if only one
0/4 … 20 mA analogue
output is used in conjunction with an SK 545E frequency inverter and a type SK EBIOE-2 (275900210) IO extension.

2.2 Technology units
The technology units are available as optional extensions for the modular slot on the front of the
frequency inverter. There are plug-in technology units for communications and operation/diagnosis.
The first sub-chapter presents the optional and replaceable operation/diagnosis options providing data
backup and saving functions (number of storage areas) of parameter and data records.
The second sub-chapter presents the optional and replaceable communication technology units.
These are used for individual solutions and applications for implementing the standard field bus
control systems such as PROFIBUS DP, CAN, CANopen, DeviceNet, AS-Interface, etc.
