(4) Power supply for the A2CI/0 module and the A2C special function
modules
The A2CI/0 modules and the A2C special function modules require 24
VDC power supply. Use the A66PC power supply module or a general-
purpose 24 VDC power supply.
(5) Both remote I/O modules and remote terminal modules, when used with
the A2C, need station number setting.

If two or more different modules are set for one same station number,
incorrect input and output will occur. Make sure that there are no
modules which are set for one same station number when the power is
turned ON.
See Section 4.7 for details of station setting .
