A compact converter that allows communications between RS-232C/USB and RS-422/485 devices. Ideal for industrial applications.

• Allows communications between RS-232C/USB (Universal Serial Bus) and RS-422/485 devices.

• Applicable in FA environments: Has passed environment resistance tests equivalent to those for control devices.

• CE marking (except for USB).

• UL/CSA certification (mark license recognition).

• Compact 30-mm-wide body supports both screw-mounting and DIN track mounting.

• Operation either with or without echoback available.

• Functionality to convert between USB and RS-232C communications added.

Note: To use USB communications, the USB driver for the K3SC must be downloaded from the OMRON web site.

Application Examples

• Data can be transferred between computers (using the USB port if there is no RS-232C port) and field devices.

• Using two K3SC Units enables long-distance communications between devices connected via RS-232C.
