The C-Bus Chanel Relay Unit is a DIN rail unit suitable for switching resistive, inductive and fluorescent loads.

The relay unit features learn mode, local and remote overrides for on/off control, Channel, C-Bus and Unit status indicators.

Load control is provided by a special mechanically latched relay, with local mechanical override on the unit. independent of the C-Bus communications. Each relay is rated at 20A, and is compatible with resistive, inductive, incandescent and fluorescent load types.

  • Provides 4 x 20A channels of switching output.
  • Programmable via the learn mode feature or using the C-Bus configuration software.
  • Programmed variables are stored in non volatile memory and are retained in case of loss of mains or C-Bus power.
  • Local and remote on/off control independent of C-Bus communications.
  • Mechanical override independent of C-Bus communications.
  • Programmable power up state following power cycling.
  • Logic states (and/or) programmable using the C-Bus configuration software.
  • Features mechanically latched relays that hold state in case of loss of C-Bus communications.
  • Designed to fit into standard 35mm top hat DIN rial. measures just 12M in size.
  • CE Compliant
