Notes:
1
Consult factory for life expectancy at other switching loads. End of life is dened as Resistance >0.5Ω, or failure to open.
2
Optional diode is connected to pin #2(+) and pin #3(-) for 9091; pin #3(+) and pin #4(-) for 9092. Correct coil polarity must be observed.
3
9091 internal mag shield. 9092 external mag shield.
