Blue Wire - RIO 1

Shield Wire - RIO SH

Clear Wire - RIO 2

ATTENTION

If this is the last adapter in your FLEX I/O

system, or the last adapter on the remote I/O link,

you must use a termination resistor across

terminals 1 and 2 on the remote I/O connector.

Refer to the information supplied with the

processor being used for information on the size

of the resistor.

2. Connect +24V dc input to the left side of the lower connector

terminal A.

3. Connect 24V common to the left side of the upper connector

terminal B.

4. Connections C and D are used to pass 24V dc power and

common to the next module in the series (if required).

Wiring when total current draw is less than 10A

Note: Refer to the individual instructions for each module for actual wiring information.

Note: Modules must be either all analog or all discrete. Do not mix analog

and discrete modules when using the daisyĆchain wiring scheme.
