Solar power & relay controller dual relay output Model 6912DR-12 regulates the charging of a 12V sealed lead acid battery via a solar panel and provides a supervised 12V power output. In addition to this, controller has two 2A relays with capacity to operate either solenoid or small pump. Any Unidata logger can interface with the controller allowing program control of the two relay outputs.
