Rockwell Automation Allen-Bradley 1794-IB16D - Wiring Output Loads

30 Rockwell Automation Publication 1794-UM061B-EN-P - March 2020
Chapter 3 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 daisy chained 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).
