Wiring the ICAD actuator There are two cables which are connected to the ICAD motor with M12 connectors:
Supply voltage is galvanically isolated from input and output wires
Supply Voltage Fail Safe Supply
24 VDC + 10%/-15% Min. 19 VDC
Load ICAD 600A 1.2 A ICAD 600A 1.2 A
ICAD 1200A 2.0 A ICAD 1200A 2.0 A
Analog Input – Current or Voltage Analog Output
Current 0/4 – 20 mA 0/4 – 20 mA
Load: 200Ώ Load: ≤ 250 Ώ
Voltage 0/2 – 10 VDC
