When using the CA-DC21E and the CC-Link expansion unit at the same time
Connect the CC-Link expansion unit CA -NCL10E directly to the controller, and then
connect the CA-DC21E to the left side of the CC-Link expansion unit.
[For the CV-5000 Series]
„ Terminal interface
„ Input circuit diagram
„ DIP switch configuration
The output voltage for illumination can be changed by changing the DIP switch
configuration.
The factory default configuration of the DIP switch is shown with „.
The output voltage can be changed individually for illuminations 1 and 2. The output
voltage at that time is common between the connector and the terminal block.
*1 The environmental resistance for the LED illumination unit is surrounding air
temperature: 0 to 40 o C, and surrounding air humidity: 35 to 65% RH (No
condensation).
*2 The temperature range depends on the surrounding temperature of the connected
controller.

E 1110-2
The CC-Link expansion unit cannot be connected to the left side of the
CA-DC21E.
Incorrect output voltage settings may cause fire, electric shock, or
product damage. Use 12 V (factory default) when connected to a
KEYENCE emitter.
