Getting started with LOGO!
Which devices are available?
LOGO! Base Modules are available in two voltage classes:
● Class 1 ≤ 24 V, i.e. 12 V DC, 24 V DC, 24 V AC
● Class 2 > 24 V, i.e. 115...240 V AC/DC
LOGO! Base Modules are available in two versions:
● LOGO! Basic (version with display): 8 inputs and 4 outputs
● LOGO! Pure (version without display): 8 inputs and 4 outputs
Each version is integrated into four (if 0BA6) or six (if 0BA7) subunits, is equipped with an
expansion interface and LOGO! TD interface and provides 39 (if 0BA6) or 44 (if 0BA7) pre-
configured standard and special function blocks for the creation of your circuit program.
Note
The LOGO! 0BA7 Base Modules currently released are only the LOGO! Basic version.
Which expansion modules are available?
● LOGO! digital modules DM8... are available for operation with 12 V DC, 24 V AC/DC and
● LOGO! digital modules DM16... are available for operation with 24 V DC and 115...240 V
● LOGO! analog modules are available for operation with 24 V DC and some with 12 V DC,
The digital/analog modules are integrated in two or four subunits. Each one is equipped with
two expansion interfaces for connecting additional modules.
Which display modules are available?
● LOGO! Basic
● LOGO! TD

depending on the specific module. Each is equipped with two analog inputs, two PT100
inputs, two PT100/PT1000 inputs (either PT100 or PT1000 or one of each), or two analog
outputs.
