          Illumination Controller

          CA-DC Series

          CA-DC Series

          Minimal wiring
          CA-DC30E (For XG/CV-X Series only. For use when combined with the CA-DRWxX Series only.)
          CA-DC21E (Dedicated for CV-5000/XG/CV-X Series) CA-DC10E (Dedicated for CV-X100 Series)

          Minimal wiring

          The LED lighting controller can be connected directly to the vision system with the minimal amount of wiring required. The controller enables direct illumination control and light strobing in conjunction with image capture trigger inputs without the need for a PLC. Up to 4 illumination expansion units* can be connected to a single vision system, enabling up to 8 lights to be connected in any combination without wiring.

          * This applies to the case when the CA-DC21E is used. When the CA-DC10E is used, only 1 unit can be connected. When the CA-DC30E is used, up to 2 units can be connected (additionally, 2 CA-DC21E units can be mixed in).

          Strobe lighting

          LED illumination is the norm for machine vision due to its flexibility and lifetime characteristics. However due to complex wiring and sequencing the fast switching performance of LED’s may not be maximised and the light is left continuously on. The CA-DC30E/CA-DC21E/ CA-DC10E automatically enables strobing of light sources by default without the need for wiring or complex programming. This results in a significantly longer service life.

          Precautions for using LED illumination

          • Continuous use of LED illumination at high temperature and high humidity accelerates light intensity reduction and deterioration.
          • Reduce heat emission from illumination.

          Use the limit function and the light adjustment trimmer.
          If LED illumination is used at the maximum light intensity, illumination emits a large amount of heat, which will affect the service life. It is recommended that the limit function should be turned on, or the light adjustment trimmer should be set to approx. 40 to 60%. (Standard feature of CA-DC100)
          Turn on LED illumination only when capturing images.
          It is recommended that the external ON/OFF switching function should be used to strobe lights in synchronisation with image capturing.
          * LED’s do not deteriorate or burn out like normal lights when pulsed at a high ON/ OFF frequency.
          Use LED illumination in an environment that ensures easy heat radiation and cooling.
          Installation of a cooling air blower and fan, and using mounting brackets with high heat conductivity are effective.
