KCX-B series	KCV series	remarks
KCX-B4W	KCV-4S	4-digit AC power supply
KCX-B4WM
KCX-B6W	KCV-6S	6-digit AC power supply
KCX-B6WM

The external dimensions are different. (KCX: 72mm □ → KCV: 48mm □)

2. The maximum counting speed is different. (KCX-B: 20kHz → KCV: 10kHz)

3. The output current of the power supply for the sensor is different. (KCX: 80mA → KCV: 60mA)

4. The KCV transistor output cannot be used in positive logic (PNP).

5. The terminal block arrangement and setup method are different between KCX-B and KCV.

6. KCX has no contact output / contact output for the first set value,

There is also a non-contact output / contact output for the second set value,
For KCV, the output of the first set value (with prediction output) is non-contact output,
The output of the second set value is the contact output.

If the contact output is used for the KCX-B’s first set value output, an external relay is required at the time of replacement.

If a non-contact output is used for the second set value output of KCX-B, it will be a contact output after replacement.

Both KCX-B / KCV are set with each digit key.

When replacing mode 0 (hold output / count continuation), SW5 of KCV is set to ON.
KCX-B □ Dip SW4 (input / output logic) settings are set in the KCV setup mode.
* The transistor output of KCV cannot be used in positive logic (PNP).
