JFBM Battery Monitor GSM Communicator

 
The Battery Monitor JFBM has been designed to monitor 3 different battery voltages with settable upper and lower limits.
The JFBM operates on 10 to 16 VDC and this is the first input that is monitored and normally set
For a low battery on 10.7 vdc and 12.5 Battery OK.
The 2 other inputs can be set to monitor any voltages from 2 to 70 vdc.
 
E.G.
24.0 and 27.0 for the 24 volt input. Settable between 1 and 70 VDC
48.0 and 57.0 for the 48 volt input. Settable between 1 and 70 VDC
In Addition to the inputs the JFBM has 1 x 10 Amp relay output that can be controlled by SMS, Drop Call and Timers.
Messages from the inputs can also be routed back to the JFBM to operate the relay.
E.G On a battery low the message can be routed back to the JFBM to operate the relay for a charger etc.
Similarly the Battery ok can switch off the charger.
