(3)Fast turn-off modules (1746-OB6EI, -OBP8 Series B and later, -OB16E Series B and
later, -OBP16, and
-OVP16) provide fast OFF delay for inductive loads. Comparative OFF delay times for
1746-OB8/-OV8 and fast turn-off modules, when switching Bulletin 100-B110 (24W
sealed) contactor, are: 1746-OB8/-OV8 OFF delay = 152 ms; fast turn-off modules OFF
delay = 47 ms.
Off State Leakage (max.)

(4)To limit the effects of leakage current through solid state outputs, a loading resistor can
be connected in parallel with your load. For transistor outputs, 24V dc operation, use a
