The PLC Alternative Programmable Automation Controller
The WL-MIO is the "Big Brother" to the popular PI-SPI and PI-SPI-DIN series of industrial automation I/O interfaces for the Raspberry Pi. The WL-MIO offers:
NEW Modbus TCP Gateway software for CODESYS and OpenPLC Support!
Analog and Digital I/O Modules
All modules can be "Hot Swapped"
Raspberry Pi 4 Main Processor
PLC Replacement or Alternative
Open Source Software Libraries Available for C, Python, Node-RED and Modbus TCP Gateway
Scalable up to 16 Backplanes and 1000+ I/O Points from one Raspberry Pi 4
The Backplane has high density wiring capability to:
"Land the Wires One Last Time"
PLC Starter Kits for the Raspberry Pi
PLC Starter Kits are now available for automation projects. Three input styles are featured:
8 Channel 4-20mA Input.
8 Channel Temperature Input
8 Channel Isolated Digital Input.
Each Kit comes with a 4 channel relay output module, power supply and DIN rail
New Product Release VP-KB1
VP Process inc. has releassd a new Industrial Controller for Gas Detection Applications based on the Widgetlords PI-SPI-DIN series of products.
Comes complete with a Raspberry Pi, SD card preloaded with the application software and an IP66 rated enclosure with a separate access door for the LCD display.

8 Channel Analog Input 16 Bit ADC for the Raspberry Pi
The brand new PI-SPI-8AI-16B analog input interface is now shipping.
8 Channels of 16 Bit 4-20 mA analog input for your Raspberry Pi, each channel easiy convertible from mA to VDC to Thermistor Input.
Up to 4 modules can be connected to one Raspberry Pi for a total of 32 analog 16 bit ADC inputs.
DIN rail mountable using the the VPE-4450 mounting kit.
DIN Rail Mounting Kit for the RPi
Here is a simple way to mount your Raspberry Pi onto a DIN Rail. The kit contains everything you need - pcb (same footprint as the RPi B+), DIN clips, spacers and screws.
Featured Product - LCD Cable Kit
The 4100/10PCB Ribbon Cable Extension Kit allows the Raspberry Pi 7" Touchscreen LCD Display to be mounted up to 18" away from the Raspberry Pi.
It's the perfect addition to a Raspberry Pi based control system.
4 - 20 mA Analog I/O
Hi-Density PI-SPI-DIN Application
The Raspberry Pi is being used in automation applications every day. This picture was taken by our friends at Lockheed Martin Corp. of one of their simulation systems using our PI-SPI-DIN series of products.
The Pi-SPI-DIN series has 4-20mA Inputs, 4-20mA Outputs, Isolated digital Inputs, Relay Outputs, RS485 and a Real Time Clock.
