KCN-S series	KCV series	Remarks
KCN-4ST	KCV-4S	4-digit AC power supply transistor output
KCN-6ST	KCV-6S	6-digit AC power supply transistor output
KCN-4ST-C	KCV-4S-C	4-digit DC power supply transistor output
KCN-6ST-C	KCV-6S-C	6-digit DC power supply transistor output

1. The maximum input speed is different. (KCN-S:5kHz -> KCV:10kHz)
2. The terminal block arrangement and setup menu items / display order are different between KCN-S and KCV.
3. The key protection method is different.
4. KCV will not output, if the set value is 0.
5. The depth dimension of the product is different. (AC power supply: + 10mm, DC power supply: + 5mm)
6. Set the KCV with prediction output setting to “zero”.

Output mode	Replaceability
Mode 1: Hold output / continue counting	Available
Mode 2: One-shot output / count reset	Available

KCN-Both S / KCV are set with each digit key.

The setting order of the setup mode menu is different between KCN-S and KCV.
In addition, some functions have changed to DIP SW settings.
