Negative Logic: device code suffix “1”
Logic Low = module On, Logic High = module Off
Positive Logic: No device code suffix required
Logic Low = module Off, Logic High = module On
Logic Low Specification
Remote On/Off Current – Logic Low

Case 1: On/Off input is set to Logic high and then
input power is applied (delay from instant at
which VI = VI,min until Vo = 10% of Vo, set)
Case 2: Input power is applied for at least one
second and then the On/Off input is set to logic high
(delay from instant at which Von/Off = 0.9V until Vo
= 10% of Vo, set)
Output voltage Rise time (time for Vo to rise from
10% of Vo, set to 90% of Vo, set)
