PiXtend V2 -L- (LARGE) Extension Board - PLC


PiXtend V2 -L- is a programmable logic controller (PLC) based on the powerful Raspberry Pi single board computer. It‘s numerous digital and analog inputs and outputs allow connections to a wide range of sensors and actuators found in industrial applications and in the Maker scene. The connection to other devices, controls and computer systems is established via standard serial interfaces (RS232, RS485, CAN, Ethernet, WiFi & Bluetooth).
All interfaces and I/Os have a robust design and comply with the PLC standard (IEC 61131-2).


PiXtend V2 -L- Extension Board

The Extension Board variant is intended for private persons and school institutions which already have a Raspberry Pi B +, 2 B, 3 B or 3 B+. No Raspberry Pi is included in the delivery, but all the components which are needed to connect and mount the computer. No soldering is necessary.
This gives you the full PiXtend V2 -L functionality in the form of an expansion board at the lowest price. For the operation you need a suitable power supply, one of the Raspberry Pi variants and a microSD card.

Supported Software:

  • CODESYS V3 - professional programming system for programmable logic controllers (PLC) according to IEC 61131-3
  • C - the standard of the Linux world
  • Python - the language of the Raspberry Pi, scripting language
  • FHEM - popular open source home automation system, operation via web or app
  • Node-RED - graphical flow-based programming for the IoT age
  • OpenPLC - free system for PLC programming according to IEC 61131-3
  • Comming Soon: FourZero - the programming system for distributed control systems and Industry 4.0 according to IEC 61499
