5.3.3 Connecting the outputs
Depending on load type and current the STG-115 is able
to directly drive electric loads without any additional driver
or protection circuit. The Mini-PLC provides 8 digital solid-
state highside outputs and one isolated relay output.
Common features of outputs OUT1 to OUT8 (X6)
• Rugged solid-state higside switch up to 1.5A
• Paralleling permissible up to 6A
• Short circuit protection and current limitation
• Fast demagnetization of inductive loads
• Stable behaviour at undervoltage
• Comprehensive integrated protection circuits
• Outstanding electromagnetic compatibility (EMC)
• Electrostatic discharge protection (ESD)
Features of output OUT9 (X5)
• Relay NO/NC changeover output type 1A/30VDC
• Electrically isolated
• Outstanding electromagnetic compatibility (EMC)
• Electrostatic discharge protection (ESD)
The 9-pole connector X4 named ‚OUT1‘ to ‚OUT8‘ contains
all digital outputs of the Mini-PLC. While OUT1 to OUT8 are
overload-protected highside switches, OUT9 (X5) is carried
out as electrically isolated relay changeover NO/NC switch.
A logical HIGH within miConL will switch the Mini-PLS´s
supply voltage at OUT1 to OUT8, while the isolated contact
of OUT9 changes over (NC/NO-NO/NC).
Aviod a current exceeding 1A/30VDC at OUT9 because this
outputs is not protected against short-circuiting or overload
current !
The total current sourced by OUT1 to
OUT8 must not exceed 6A!
Avoid reverse voltage at any output higher
than the Mini-PLC´s supply voltage!
OUT9 provides NO short circuit protection.
Take care the contact current not exceeds
1A! Negligence may cause irreversible
damage of the Mini-PLC!

OPERATION AND PROGRAMMING
To operate the STG-115 first establish proper power supply
connection at both +VDD and GND terminals.
For programming and PC connection the connection cable
VK-12 (Art. No. 0091-0012) and a PC with installed Windows
operating system are mandatory.
Before you connect the Mini-PLC to the PC you have to ins-
tall the USB-/COM-port driver (folder ‚USBdriver‘) from the
software download package:
www.barth-elektronik.de/download/9045-0008-A.zip
Now install the miConL software suite from the ‚miCon-L‘
folder. Follow the setup instructions of miConL. Afterwards
establish the PC connection using the VK-12 connection
cable and run miConL.
For choosing the correct COM-Port please click the right
button (configure serial interface) located on the main menu
page and confirm the added COM-Port used by the STG-
115.
Now start miConL with creating a new project (Project->
New) or open a miCon-L sample application (Project-
>Open).
