Digital Outputs Every single Digital Output (O0, O1, O2 and O3) can be used in a NPN- or PNP-
configuration depending on your application needs. This configuration is done by
making the corresponding DM-setting (refer to 3-5-4
"Output Control Configura-
tion" 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.
Digital Inputs The Digital Inputs should be supplied with 24 VDC signals. Every Digital Input (I0,
I1, I2 and I3) is equipped with a separate Ground Signal (0V) and has its own elec-
tronic 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).
Counter Inputs 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 24VDC signals from NPN- or PNP Drivers
The Unit allows you to connect Line Driver signals and 24VDC signals to any
Counter. To the CS1W-CT021, 5VDC and 12VDC signals can be applied only to
Counters 1 and 2 respectively. The CS1W-CT041 allows connecting 5VDC and
12VDC signals only to Counter 1 and 3 and Counter 2 and 4 respectively. The fol-
lowing table gives an overview of which driver signals can be applied to which
Counters:

2-3-2 Connector Wiring Methods
!Caution
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.
!Caution
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 CS1W-CT021/CT041 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
