Line Seiki Co., Ltd.
Pulse Generator for Length Measurement CT1 Series
A Collection of Wiring Samples
NOTE 1:
When you use a CT1 unit with an electronic counter made by other manufacturer than Line Seiki and/orwith PLC, we kindly ask you for your perusal of wiring methods described on their instruction manuals.
There is a possibility that they recommend a wiring method that is different from what is described on thisdocument.

NOTE 2:
Any breakdown and/or damage caused by miswiring is out of warranty.

If the following condictions are applicable, please select open-collector input by connecting terminals #10 & 11 of G90/G95 counter.
- CT1-A unit connects to G90/G95 counter.
- Power source for CT1-A unit is provided by G90/G95 counter.

NOTE:CT1-ACH unit requires 24VDC as its power source, therefore, it is not possible to utilize power source of an electronic counter.
Please provide external power source to CT1-ACH.

NOTE:

It is possible to connect CT1-A unit to an electronic counter and make open-collector input.
Please supply power source of 12VDC to CT1-A unit from the electronic counter.
