NOTE:
This output is supplied
with an arc suppression
snubber across the
output terminals. High
impedance loads may
remain energized even
though the output device
is turned OFF.
NOTE:
Minimum load resis-
Ω
tance is 500 . Available
current is 22mA
maximum. Typical
voltage drop across a
Ω
1K load is 12 to 19
volts.
