Rockwell Automation 2755 AdaptaScan Bar Code Readers - Manual (Page 18)

Overview 1–10
Reader Connector
The Reader plugs into this connector. All power and
communications with the Reader occurs through this connector.
I/O Module Sockets
Two sockets support any combination of the following input and
output modules. See specifications in Appendix A.
Description Catalog Number
DC Output Module – rated at 3 to 60 VDC. 2755-OB5S
AC Output Module – rated at 12 to 140 VAC. 2755-OA5S
AC Output Module – rated at 24 to 280 VAC. 2755-OM5S
DC Input Module – accepts 3.3 to 32 VDC. 2755-IB5S
AC/DC Input Module – accepts 90 to 140 VRMS or VDC 2755-IA5S
AC/DC Input Module – accepts 180 to 280 VRMS or VDC 2755-IM5S
I/O Module Terminal Blocks
Wiring connections for the optional input or output modules.
Package Detect Terminal Block
Connects the contacts of a sensor, which detects the presence of a
package in the Reader’s scan area. The package detect can be either
an electronic (current sinking) or a hard contact type device. Most
applications use a photo-reflective type sensor. The package detect
starts and stops decoding and determines when messages are sent or
when outputs are energized.
Power – Indicator LED
Indicates normal operating and fault conditions.
Condition Indicates:
Green Power on.
Red Polarity of the power connections is reversed. Wiring must be
corrected.
Off No power.
Termination Switches
Terminates a DeviceNet and RS-422/RS-485 network. Terminate the
two devices furthest away from each other on a network by moving
the switch to the ON position.
