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.]
