16. LOW POWER / BATTERY OPERATION

By the use of current limiting resistors on the inputs of the GSM Commander and Expansion Units,
the   GSM   Commander   can   operate   more   efficiently   in   terms   of   current   consumption.   This   is

particularly important when the GSM Commander is powered by means of a battery connected to a
solar panel or any other alternative source of power generation.

To connect a  switch  or contact  to an  input, simply connect the switch between the + and +IN
terminals, and a 

5k6

 resistor between the – and IN– terminals. The reverse is just as suitable, i.e.

that you connect a 

5k6

 resistor b and +IN and place the switch between – and IN–. This will

decrease each input's current consumption (when active) from 25mA to 2mA. 

Similarly a 

5K6 

resistor can be connected to all the inputs of the Expansion Unit(s) to decrease each

input's current consumption (when active).

Please Note:

 The above results were obtained by connecting a 14V switching power supply to the

GSM Commander.
