Designed primarily for the Fire and Rescue markets, the System 21 6 Way is a six function relay control board that load sheds and turns on circuits in sequence (Sequencer Load Manager is required and sold separately).
The six-way board can include either socketed relays for lower amp relays (30/40) or soldered on relays for higher amps (70). The 6 Way board incorporates LED status indicators on the inputs and outputs, as well as a fault light for easy diagnostics.
