Digital outputs

Digital output have PNP open collector output static signal, totem pole for pulse signals.
Digital output current is max. 25 mA continuous and 50 mA for short time, 13 ms.
The output is short circuit protected and protected against voltage transients caused by
inductive loads.
If the digital output is overloaded, it will be turned off after 13 ms and once a second the
output will be activated again.

19.5. LCP cable length

Max. distance between LCP2 and FCD300: 3 m.
