The Sentinel GPS BPR-1a PB Basic Power Relay helps controllers and timers coordinate equipment in gardens, greenhouses, and grow rooms. Its two operating modes provide flexible control of connected devices.
In Normally Off mode, a trigger cable activates connected equipment, allowing a controller or timer to operate multiple devices or manage a higher amperage load. In Normally On mode, the trigger cable switches connected equipment off. For example, coordinate CO₂ equipment with ventilation fans by switching the CO₂ equipment off when the fans activate.
