PiXtend eIO is the I/O extension system for those who are looking for low-cost, general-purpose inputs and outputs - digital & analog.
The data connection is made with the robust RS485 bus. If not available, it can be retrofitted to any computer system. The eIO modules and their inputs and outputs comply with the industry standard IEC 61131-2 and are therefore intended for use in rough environments as found in laboratories, the industry and manufacturing companies. Compliance with the worldwide acknowledged industry standard has great advantages in terms of stability and immunity to interferences. All common sensors and actuators can be easily connected to the eIO devices.
Innovative features, such as the particularly fast digital "Hyper Logic", bring additional added value to your project. Simple logical connections between inputs and outputs can be carried out by the modules themselves without the need for data transmission via the bus. Digital inputs can also be used to count events.
A watchdog timer monitors the data transmission secured by a CRC checksum and, if necessary, puts the outputs in a user pre-set safe state.
The eIO system blends optically, haptically and functionally peferct with our PiXtend V2 controllers (-S- and -L-) - but can also be connected to almost any other computer system & embedded system that has an RS485 interface or can be retrofitted with it (eg via USB).

Also in terms of communication and protocols, PiXtend eIO is simple and user-friendly. With Modbus RTU support, eIO devices also integrate well with existing systems. The protocol is safe and industry-proven for years. In addition, the eIO devices can be used with the particularly simple and slim "PiXtend eIO Protocol", which transmits the data in plain text (ASCII). We offer open source example programs for C, C#, Python, CODESYS (61131-3), Java and Node-RED. The integration into your own applications is a breeze.
The basic settings can be carried out directly and uncomplicated on the device itself - without software or any tool and without previous knowledge of the local service personnel.

Variant: PiXtend eIO Digital One Pro
The PiXtend eIO Digital One "Pro" devices are complete units (ready-to-use) which, in addition to the scope of the "Basic" variant, also have a stainless steel cover and DIN rail housing. This version is particularly suitable if the devices are to be installed in a control cabinet and the industrial application is in the foreground. This eIO Digital One variant is aimed at customers with the highest demands on optics, stability and security.
Digital One has 8 digital inputs and 8 digital outputs.
Would you like to mount the devices in your own special housing and you do not need a DIN rail housing and metal cover? Then the "Basic" variant is exactly what you are looking for - at the best price!
