PiXtend is a programmable logic controller (PLC) based on the powerful Raspberry Pi single-board computer. Its wide range of digital and analog inputs and outputs allows for the connection of a wide variety of sensors and actuators from both the industrial and maker sectors. Connections to other devices, controllers, and computer systems are established via standard serial interfaces (RS232, Ethernet, Wi-Fi). All interfaces and I/Os are robustly designed and comply with the PLC standard (IEC 61131-2). In the new version 2.1-S, the features have been further optimized and innovative capabilities added: https://elecena.pl/product/13425621/50199014-raspberry-pi-plc-pixtend-v2-1-eplc-pro 2018-01-20 https://elecena.pl/product/13425621/50199014-raspberry-pi-plc-pixtend-v2-1-eplc-pro 2018-01-25 https://elecena.pl/product/13425621/50199014-raspberry-pi-plc-pixtend-v2-1-eplc-pro 2021-04-29 https://elecena.pl/product/13425621/50199014-raspberry-pi-plc-pixtend-v2-1-eplc-pro 2022-05-13 https://elecena.pl/product/13425621/50199014-raspberry-pi-plc-pixtend-v2-1-eplc-pro 2022-07-19 https://elecena.pl/product/13425621/50199014-raspberry-pi-plc-pixtend-v2-1-eplc-pro 2022-12-03 https://elecena.pl/product/13425621/50199014-raspberry-pi-plc-pixtend-v2-1-eplc-pro 2023-01-30 https://elecena.pl/product/13425621/50199014-raspberry-pi-plc-pixtend-v2-1-eplc-pro 2025-04-08 https://elecena.pl/product/13425621/50199014-raspberry-pi-plc-pixtend-v2-1-eplc-pro 2026-02-14
