Digital Output

Digital Output - 3 pcs. NPN transistor output.
External supply
7 – 24 V DC (same supply as for ICAD can be used, but please note that the galvanically isolated system will then be
spoiled).
On resistance
55 Ω + diode voltage 0.7 V DC
Max 70 Ω at 50 mA
Max Output current: 50 mA
Reverse polarity protection: Yes
Overcurrent protection: No

Wiring the ICAD actuator

There are three cables which are connected to the ICAD motor with M12 connectors:
