AC Isolated Digital Output Module
110 VAC
(T7454)
Issue 1, March, 06
The AC isolated digital output module provides control of 
eight isolated user output loads. One type of module is 
available to interface to outputs powered from isolated 110 
VAC field power supplies. Each module's triplicated I/O 
Safetybus interface ensures that no Regent system failure can 
incorrectly apply power to an output, and that no failure in 
the module can affect the operation of the Regent system or 
other I/O modules in the system.
