3.3.1 Customer unit Basic I/O
(SK CU2-BSC, Part. No. 275130010)
(SK CU2-BSC-C, Part. No. 275170010)
The Basic I/O customer unit (Customer Unit) provides an adequate number of
control signals for simple control tasks, thereby offering a budget solution for
many cases.
In addition to the controls available in the standard version, the Basic I/O has
one analogue and 3 digital inputs. The analogue differential input can handle
signals from 0...10V, 0...20mA or 4...20mA.
Note:
AGND, 0V is the reference potential for the analogue and digital
inputs.

(Maximum terminal cross-section: 1,5 mm²)
DIP switches:
You can select whether current or voltage setpoints should be used for the analogue input. Set the DIP
switches as follows.
1. Switching the
load resistor for ON = Current setpoint 0/4...20 mA
analog input 1 OFF = Voltage setpoint 0...10 V
2. Switching a bridge between ON = Bridge closed
terminals AGND/0V and AIN- OFF = Bridge open
NOTE With current setpoint setting:
Scaling must be taken into account when operating with a current setpoint of 0/4...20mA.
If 20mA represents a setting of 100%, then parameter P403 "Analog input 1 adjustment 100%" must
be set to 5V!
