KCN-A series	KCV series	Remarks
KCN-A4SR	KCV-4S	4-digit AC power contact output
KCN-A6SR	KCV-6S	6-digit AC power contact output
KCN-A4SR-C	KCV-4S-C	4-digit DC power supply contact output
KCN-A6SR-C	KCV-6S-C	6-digit DC power supply contact output

1. The maximum input speed is different. (KCN-A:5kHz -> KCV:10kHz)
2. The terminal block arrangement and setup menu items / display order are different between KCN-A 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”.

KCN-A series	KCV series
Short-circuit terminal blocks 5 and 6	Set with SW6

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

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.
