Electrical Controller Connections
4.5.1
Handling of Pluggable Screw Terminals
The controller IFC24x1 has three pluggable screw terminals for supply, digital I/O and
analog out, which are included as accessories.
Remove approx. 7 mm of the connecting wire isolation (0.14 ... 1.5 mm²).
Connect the connecting wires.
i
Use two captive screws to fix the screw terminals.

not electrically isolated, GND is electri-
cally connected to the GND wiring for
switching outputs, synchronization and
encoder input.
Use a shielded cable of less than
30 m.

LED lights up.
4.5.3
RS422
-
Differential signals in accordance with EIA-422, electrically isolated from the supply
voltage.
-
Receiver Rx with a 120 ohm internal terminating resistor.
On the evaluation unit (receiver), ter-
minate the transmitter input (Tx) with
90 ...120 ohm.
Use a shielded twisted cable of less
than 30 m.
Connect the earth connections.

Ethernet, EtherCAT
Potential isolated RJ 45 standard connector for connecting the
controller IFC2451/2461/2471
-
to an Ethernet network (PC) or
-
the EtherCAT bus system (IN-Port).
Use a shielded Ethernet cable (Cat5E, patch cable, 2 m,
included in the delivery, overall cable length less than
100 m to connect controller and network.
Both LEDs on the plug-in connector light up to indicate that
the connection was successful and is active.

The measuring device can be configured through the web interface or using ASCII com-
mands (e. g. Telnet), see Chap.
or with EtherCAT objects.
