Last summer Pi-oT introduced a Raspberry Pi add-on board of the same name targeting commercial & industrial IoT automation. The project was launched on Kickstarter and backers should have received their rewards.
The DIN-rail enclosure included with the RPi HAT was popular, so they decided to work on a Pi-OT MKR module enclosure with a similar form factor but instead of using screw terminals for ADC input and relays, they routed some of Raspberry Pi GPIO pins to the terminal, added a breadboard to the case for prototyping, as well as a fan for cooling.
