Thanks to expansion HAT small and cheap Raspberry Pi Zero 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 the third something to control power hungry devices such as high power relays, valves or motors, in this case I use MosfetPi 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
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
Input/output HAT for Raspberry PI. The NO relay output can switch on and off AC/DC circuits. The input can detect state of switch or relay connected between PLUS (+) terminal and INPUT terminal
Can be delivered with or without soldered gold-pins connector, one 20 pin female connector is included and one 2 pin, one 20-pin male connector
Why did you make it?
To receive signals from or control elements of environment, for example to receive signal from ordinary motion sensor and be able to turn on alarm siren and make from Raspberry PI simple alarm
What makes it special?
It’s cheap simple and durable
Technical specs:
output relay: NO 10A 250VAC/10A 30VDC
input: 500mA 40V
dimensions: 97x56x22mm
frame for mounting: DIN TS35 rail
protection: each board is protected by PVE lacquer
Installation to monitor and notify level of water in large tank
Everything is based on industrial components except the Raspberry PI which is the brain of this installation, and JAVA application which makes all the magic
Raspberry PI is powered by buck converter, soldered by wires to control pads on Raspberry board, micro USB connection is so unreliable, Pi and converter are on the same board attachable to TS35 rail, to communicate Pi is using GSM modem attached to GPIO header, modem is based on SIM868 module
To measure water level I’m using hydrostatic probe and network attached converter 4 – 20 mA signals
Readings are visualized on publicly available internet site, off cours password protected, in the same manner installation can be controlled. If alarm levels are reached device will send SMS to programed recipients
