NOTICE
Maximum input current!
The maximum input current of the switching input is 8 mA.
NOTICE
Maximum loading of the switching output!
The switching output is protected against short-circuit, overcurrent, overvoltage, excess temper-
ature and transients.
Ä
Do not load the switching output with more than 60 mA at +18 … +30 VDC.

Connection cable shield
The shield of the connection cable is on the thread of the M12 socket.
The thread of the M12 socket is part of the metallic housing. The hous-
ing is at the potential of the functional earth via pin 5 of the POWER
connector plug.
Connection cables: see chapter 13.2 "Cables accessories"
NOTICE
The device supports a transmission rate of 100 Mbit/s in full duplex mode as well as auto-cross-
over.
NOTICE
The entire interconnection cable must be shielded.
The shielding connection must be at the same potential at both ends of the data line. This
serves to prevent potential equalization currents over the shield and possible interference cou-
pling through compensating currents.
Ä
Use at least a CAT 5 cable for the connection.
