2-3-1 Connector Pin-layout
The two 40-pins connectors (CN1 and CN2) on the front of the Unit are both
divided in Row A and Row B, each row containing 20-pins as indicated on front of
the Unit. The Digital Outputs, Digital Inputs and the Counter Inputs of the Unit are
logically grouped together and allocated to the pins of connector 1 and 2. The fol-
lowing table lists the allocation of the external signals to the respective pins.
* CS1W-CT041 High-speed Counter Unit only.
Power Supply External power has to be applied to the Power Supply pins in order to feed the Dig-
ital Outputs. Depending on what your application requires you can apply an exter-
nal voltage between 12 to 24VDC. The Power Supply lines (+PS) of CN1 and CN2
are internally connected, as are the 0V lines (-PS). In this way the power only has
to be applied to one pair of +PS/-PS lines on CN1 or CN2. In case the Digital Out-
puts are not used in your application, no external power has to be supplied.
