Thanks to expansion HAT small and cheap Raspberry Pi Zero or 2-4 can be used as industrial automation controller

First of all the power, HAT that will deliver 5V to raspberry pi and other extensions, in this case PowerPi that can deliver up to 3A of current from source 8-24V

Secound we need something to recieve information in analog and digital form from the world, in that case we use two extensions the DigitalPi and AnalogPi, both are 5V tolerand, the first digital in/out and secound analog input. ADC is MCP3008 but MCP3208 can be used

And something diferent to control power hungry devices such as high power relays, valves or motors, in this case I use MosfetPi for Raspberry PI 2-4 with 8 output channels with IRF540N high power mosfet

Network automation controller with one 250V 5A relay output and two digital inputs detecting the change of short-circuit to power supply, optionly can be supplied with headers for 3 digital input\output and UART, I2C, 5V, 3V3.

In „two” simple words small device that give you ability to control or recieve signal from real world, over the network by your app using simple URL addresses,or with different firmware can be used to endless kinds of applications

In this particular situation is used as watchdog to network devices, this little device can switch off power in case of permanent hangs of monitored devices

Technical specs:

• power supply: DC12V 60mA
• relay output: NO 250VAC 5A / 30VDC 5A
• analog inputs: 2x monitoring state of the switch, contactor, relay, 12V 1.5A
• LAN standard: 10Mb/s FD
• dimensions: 79x77x19mm
• frame for mounting: DIN TS35 rail
• MCU: Atmega 328PU
• protection: each board is protected by PVE lacquer
• can be mounted in blocks on TS35 rail or on a custom mounting plate

And some image to illustrate example application

If you did not require responsiveness that offers PLC driver you can use much cheaper solution as Raspberry pi with HATs

I will present you simple adaptation of this theory, Raspberry pi as a industrall water pomps driver

What I used:

• Raspberry PI 2+ (generates less heat and is more relayable on harsh conditions)
• Power HAT of my project (suplys 5V 3A to run Raspberry pi, from any voltage witin range of 9-24V)
• MOSFET HAT witch will turn on and off 12V to switch on and off industrial relays, witch then will turn on and off softstart devices to run the pomp
• Bufferd power suply
• Custom 3D printed case
• GSM module to comunicate with HTTP server to recieve commands and store telemetrics data

And the software which is most important, all function are implemented by JAVA app, that runs on modified Raspberin OS

The modification concentrate on less use of the SD card, less write cycles, I acomplish this by creating ram drive that holds system logs, and removing all not needed services and software that can afect responsivness and consumes precious write cycles

Raspberry pi is equipped in heat spreader and protected by PVE lacquer

Raspberry PI is quite robust little device and can withstand very hard environment, but my current projects are based on Raspberry PI Zero witch is cheaper smaller and generates less heat and need less power, missing ETH connectivity can by fixed by simple HAT based on ENC28J60-I/SP

Very flexible vice that can hold elements during machining assembling, initially created to hold PCB board during SMD soldering

Consists of 22 parts can be adjusted to fit most of modern phones and phablets stand can be pivoted and tilt in all angles

size: 220mm x 220mm x 180mm
