OUTPUT UNITS |
4 Channel 20A Relay Range
Learn Enabled
The 4 channel relay units are DIN rail mounted units suitable for switching resistive, inductive and uorescent loads.
These relay units feature learn mode, local and remote overrides for on/o 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 uorescent load types.
The relay units are available as passive and current sourcing models that source up to 200mA to the C-Bus network.
