KCN-A□ST-□ replace



I would like to replace KCN-A □ ST- □.
Please tell me the successor model and update procedure when updating to the current product.



The successor model will be the KCV series.
Since there are differences in specifications, please check the following notes when replacing.


Model number comparison table

KCN-A series KCV series remarks
KCN-A4ST KCV-4S 4-digit AC power supply transistor output
KCN-A6ST KCV-6S 6 digit AC power supply transistor output
KCN-A4ST-C KCV-4S-C 4-digit DC power supply transistor output
KCN-A6ST-C KCV-6S-C 6-digit DC power supply transistor output


1. KCV does not support PNP output. For NPN open collector connection only.

2. The maximum counting speed is different. (KCN-A: 5kHz → KCV: 10kHz)

3. Set the KCV with prediction output setting to “zero”.

4. The terminal block arrangement and setup menu items / display order are different between KCN-A and KCV.

5. The key protection method is different.

6. KCV will not output, if the set value is 0.

7. The depth dimension of the product is different. (AC power supply: + 10mm, DC power supply: + 5mm)

Preset value

Both KCN-A / KCV are set with each digit key.
For KCV, set the prediction output setting to “zero”.

Settings in setup mode

The setting order of the setup mode menu is different between KCN-A and KCV.
In addition, some functions have changed to DIP SW settings.
For set-up please refer to the figure below.
