The KC-851 board is a 0-10V communicating BACnet and LonWorks K8 series dimming controller.

  • The KC-851 dimming card system allows complete control of any lighting system that involves control via 0-10V. Functions such as standard raise/lower, scene selection as well as daylight harvesting are easily configurable.
  • Compatible with the K6 BACnet and K8 Lonwork s systems, the sophisticated dimming control allows seamless integration into a BAS. Combined with the Cristal KS-86x switch and a light level sensor, the KC-851 dimming card allows not only complete control but can contribute to reduced energy consumption.
