28 About the FLEX I/O Diagnostic Output Module
Wiring Output Loads
You can use the 1794-OB16D diagnostic module with the 1794-TB2,
1794-TB3, or 1794-TB3S terminal base units.
User power can be wired to the (+) voltage and common terminals directly, or
power can be daisychained from the FLEX I/O terminal base units on the
DIN rail. Output channels are not isolated from one another. All 16 channels
share a common return (group isolation from FLEX I/O system-side logic
voltages).
