This guide provides basic installation information for specific UniStream

®

 PLC models with 

built-in I/O. Technical specifications may be downloaded from the Unitronics website. 

General Features 

Unitronics’ 

UniStream

®

 PLCs are DIN-rail mounted Programmable Logic Controllers (PLCs) 

with a built-in I/O configuration.  
The series is available in three versions: Pro, Standard, and Basic.  
Note that a model number that includes: 

 

B10/C10

 refers to Pro version (e.g. USC-B

10

-T24) 

 

B5/C5

 refers to Standard version (e.g. USC-B

5

-RA28) 

 

B3/C3

 refers to Basic version (e.g. only for USC-B

3

-T20)
