3.3.5 I/O Extension, SK CU4-IOE
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:
Bus status, bus fault
• DIP switches for selection
0-10V, -10-10V, 0-20mA, 4-20mA
• Details in Bus Manual BU 0250 (www.nord.com)
