OPT-SNAP-AOD-29

SNAP-AOD-29 SNAP 2-Ch 5-60 VDC Time-Proportional Digital Output Module

The SNAP-AOD-29 module provides two channels of time-proportional output (TPO). The module converts an analog
value, such as a PID loop outpoint, to a digital on/off output. The outputs are used to switch or control DC loads such as
lamps or indicators, solenoids, relay coils, and PLC logic.
 
Each TPO channel can switch 0.5 A of load current ranging from 5 VDC to 60 VDC, over a period range of .25 seconds
to 64.25 seconds.
 
NOTE: The SNAP-AOD-29 module is not needed for intelligent remote SNAP I/O used with Allen-Bradley PLC systems
(IO4AB). Instead, use the built-in TPO function in the brain itself.
