Outseal is an automation technology brand made by the Indonesian Engineers. Outseal products include PLC (Programmable Logic Controller), HMI (Human Machine Interface) and other modules. The outseal PLC is made based on the Arduino bootloader and the hardware design is open to the public, meaning that anyone can get and study the electronic circuits freely and make their own at home using the Arduino microcontroller board at an affordable price. And what's interesting is that the software is in the form of a visual program (ladder diagram), in Indonesian and also made free.
