QCL-LCXXXX Lighting System

COSYS Building Controls


Our COSYS Application and System Controls work along with our enterprise software platform OspreyFMS to provide a meaningful context.

The QCL-LCXXXX series are fully programmable, Native BACnetÆ Advanced Application Controllers that communicate on Twisted-Pair Ethernet 10-BaseT using BACnet IP and BACnet over Ethernet, or on a BACnet MS/TP RS-485 LAN. Specifically designed for lighting applications, this controller has up to 36 outputs and supports up to 4 industry proven Panasonic lighting relays per output. It also supports BACstats connected on its LINKnet subnetwork for network switches or field modules.


  • Native BACnet Firmware
  • BACnet IP and BACnet over Ethernet communications
  • Supports switching a maximum of 4 Panasonic relays per relay output
  • Software monitoring of switch activity
  • Supports a subnet of up to 12 BACstats
  • Up to 9 Panasonic relay switches or dry contact master inputs
  • One universal analog input
  • Individual output status indication via LED
  • Supports a master override switch with built-in sequencing
  • Fully programmable in GCL+
  • Application database and controller firmware can be flash loaded over the network
  • Easy-to-mount housing


The QCL-LCXXXX is suitable for controlling up to 36 light-ing zones, switching a maximum of 144 Panasonic lighting relays.
The controller can be mounted in various Panasonic relay enclosures for both new and retrofit construction projects.
The QCL-LCXXXX is fully programmable: GCL+ programs and BACnet objects can be created and/or modified for specific lighting applications.
