Parameter Value
Internal supply Via I/O bus
External supply Via the terminals L+ (process voltage 24
VDC) and M (0 VDC); the M terminal is con-
nected to the M terminal of the CPU via the
I/O bus
Electrical Connection
For a detailed description of the mounting, disassembly and electrical connec-
tion of the module, please refer to the System Assembly chapter

Chapter 2.5
“AC500-eCo” on page 1192.
If the output is configured as not used, the voltage and current output signals
are undefined and must not be connected.
The electrical connection is carried out by using a removable 9-pin and 11-pin terminal block.
These terminal blocks differ in their connection system (spring terminals or screw terminals,
cable mounting from the front or from the side). For more information, refer to terminal blocks for
S500-eCo I/O modules

Chapter 1.8.3.2 “TA563-TA565 - Terminal Blocks” on page 1164. The
terminal blocks are not included in the module's scope of delivery and must be ordered sepa-
rately.
The following block diagram shows the internal construction of the analog inputs and outputs:
