3.4.3 SK CU4-IOE-, I/O extension
The internal I/O units can record sensor and actuator signals. These can be used for a drive function or
forwarded to a host bus system (e.g. Profibus or CANopen).
• 2x digital inputs
• 2x analog inputs
• 1x analog output
• Status LEDs: Module status, module error,
Dig In 1, Dig. In 2
• DIP switches for selection
0 - 10V, -10 - 10V, 0 - 20mA, 4 - 20mA
• DIP switches for: addressing, bus termination
The terminal block of the Customer Unit SK CU4- IOE… is divided into two potential levels.
NOTE
Looping of the 24V supply or GND is possible, however the maximum current load of 2A
must not be exceeded with theSK CU4-IOE!
