Conditions for the load

1) The load should not be actuated by the leakage current (1 mA; 0.8 mA for receiver of thru-beam type sensor) in the OFF state.
2) The load should be actuated by (supply voltage – 4 V) in the ON state.
3) The current in the ON state should be between 5 to 100 mA DC.
[In case the current is less than 5 mA, connect a bleeder resistance in parallel to the load (shown in dotted line above) so that a current of 5 mA, or more, flows.]
