* Note: 12.0V
O
(B) device codes have an adaptable extended Turn-On Delay interval, T
delay
, as specified for B* devices. The extended T
delay
will occur when a
12V
O
module restarts following either 1) the rapid cycling of Vin from normal levels to less than the Input Undervoltage Lockout and then back to normal; or 2)
toggling the on/off signal from on to off and back to on without removing the input voltage. The normal Turn-On Delay interval, T
delay
, as specified for All
Devices, will occur whenever a 12V
O
module restarts with input voltage removed from the module for the preceding 1 second.
