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
Load: 200Ώ
Load: ≤ 250 Ώ
Voltage
0/2 – 10 VDC
Load:

Ώ
Digital Input – Digital On/Off input by means of voltfree contact with gold-plated contacts recommended
Voltage Input Used
ON: contact impedance < 50 Ώ
OFF: contact impedance > 100 k Ώ
Digital Output:
3 pcs. NPN transistor output
External Supply: 5 – 24 VDC (same supply as for ICAD can be used but note that galvanically
isolated system will be spoiled.
Output Load:
50 Ώ
Load
