Connector Wiring Methods

Every Digital Output (O0 and O1) can be used in a NPN- or PNP-configuration
depending on your application needs. This configuration is done by making the cor-
responding DM-setting (refer to 3-5-4 "Output Control Configuration" for more
details). After you have configured the Digital Outputs for NPN or PNP you should
make sure to use the corresponding physical NPN or PNP output pin.
The Digital Inputs should be supplied with 24 VDC signals. Every Digital Input (I0
and I1) is equipped with a separate Ground Signal (0V) and has its own electronic
input circuitry. This gives you the opportunity to connect sensors either with a
NPN- or PNP-output driver. By making the appropriate DM-setting it is possible to
assign multiple Digital Inputs to single Counters (refer to 3-4 "Digital Input Func-
tions" for more details).
To the Counter Inputs of the High-speed Counter Unit signals can be applied orig-
inating from one of the following driver types:
• RS-422 Line Driver
• 5, 12 and 24 VDC signals from NPN- or PNP Drivers
The Unit allows you to connect Line Driver signals and 24 VDC signals to any
Counter. The following table gives an overview of which driver signals can be
applied to which Counters:
Counter 1
Counter 2
Do not remove the label on top of the High-speed Counter Unit until the wiring
has finished. Not doing could cause wire cuttings and other materials falling into
the Unit or short circuit the internal circuitry, resulting in malfunctioning or burn-
ing. Be sure to remove the label after wiring the connectors to allow air circulation
and heat radiation.
Be sure that all the connectors are wired correctly and properly connected to the
High-speed Counter Unit, to prevent the Unit from malfunctioning.
To wire the CJ1W-CT021 in order to connect the external signals (Power Supply,
the Digital I/O and the Counter Inputs) two methods are available:
1. Directly connecting the wires and cables to the external connector, which is
standard delivered with the High-speed Counter Unit
2. Indirectly connecting the wires and cables to the screw terminals of a Terminal
Block Unit. The Terminal Block Unit is connected to the Unit with a standard
(flat-) cable. Both parts can be ordered separately.
The connector has to be assembled from the separate parts that it exists of and
that are supplied together with the Unit. Most important part is the connector jack
(FCN-361J040) that contains 40 soldering terminals to which the wires have to be
soldered.
