(5)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 (24Ws sealed) contactor, are: 1746-OB8/-OV8 OFF delay = 152 ms; fast turn-
off modules OFF delay = 47 ms.
