IOEC module configuration
Each IOEC module is configured with both analog
and digital inputs and outputs as shown in
Table 3-1.
24 V internal voltage supply
One isolated DC/DC converter supplies an overload protected voltage of 24 V (DC) to operate digital inputs from passive contacts. The output is
protected by a PTC-resistor against short-circuit
and external applied overvoltages.

Module terminals
The IOEC module has terminal blocks for internal
wiring and indicator LEDs for diagnostic and I/O
status.
IOEC DigIn adapters
The IOEC modules can be equipped with DigIn
adapters U3411 and U3412 to limit the input volt age to a certain level. The detailed settings are
described in the Wiring diagrams.
I/O device identification
The I/O modules are identified on the part with an
identification label (1), in the wiring diagram, and
in the software by the wiring diagram identifica tion number (2).
The way the identification number is built directly
corresponds to the wiring diagram as can be seen
in 3-7. The letter A represents the kind of part, an
assembly, the next three digits are the page num ber the part is located on, page 340, and the last
digit, 1, means that the part is the first assembly
on the page. This identification label number is the
key to track electrical devices throughout the drive
and in ABB documentation.
The designation for each IOEC module is shown in
Table 3-3.
