I designed this industrial control unit while working as a freelancer. It is used as an autonomous controller that performs various measurement and control tasks. It also continuously logs to internal storage and allows to adjust parameters directly on the device without using a computer. The stored data can be read out through the USB port.

I chose a dual-PCB piggyback design and an off-the-shelf DIN rail enclosure with a custom-made front plate. This allows for a very compact form factor and easy mounting.
