Product description

Unipi 1.1 is an extension board for Raspberry Pi computer which allows it to function as a programmable logic controller for monitoring, control and regulation of automation systems. The board features a universal I/O architecture with digital inputs, a set of relays, analogue I/Os and broad connectivity thanks to 1-Wire bus, I2C and UART ports 

Unipi 1.1 complete set is a practical kit containing everything necessary for installation and powerup of Unipi 1.1. Aside from the Unipi 1.1 the set also contains Raspberry Pi 4 Model B (2GB RAM) computer, Mervis software license, protective cover and other components. 

Complete set contents

Basic Unipi 1.1 features

  • 8× changeover relay (250V AC/10A; 30V DC/10A)
  • 12+2× galvanically isolated digital input (5-24V DC, min. pulse length 5 ms)
  • 2× analog input (0 - 10 V)
  • 1× analog output (0 - 10V)
  • 1× 1-Wire bus
  • 1× I2C port 
  • 1× UART port
  • RTC module (battery not included)

Inputs & outputs

Digital inputs (DI) are designed to read binary logic states represented by direct voltage levels. That makes them suitable for reading data from various binary sensors and devices such as switches (on/off), motion sensors (movement detected/not detected), liquid level sensors (full tank/empty tank) etc.

Note: By default the digital inputs 13 and 14 are inaccessible. For their use please visit this tutorial.

Relay outputs (RO) are primarily used for switching two-state devices with higher current draw such as lightbulbs, thermoelectric valve drives, water heaters, pumps etc.

Analog inputs (AI) serve for measuring 0-10V DC voltage from various analog sensors such as thermometers, pressure meters, tensometers etc.

Analog output (AO) is designed for control of various external devices by direct voltage, and is suitable for incremental control of devices such three-way valves, heat exchangers, electric motors, lighting dimmers etc.

Computing module

Unipi 1.1 complete set is powered by the Raspberry Pi 4 Model B (2GB RAM) computer.

Note: Unipi 1.1 cannot function without Raspberry Pi

Communication interfaces

Unipi 1.1 features UART port and I2C bus. The UART port can be used for serial communication with various external devices, while the I2C serves mainly for connection of the EMO-R8 relay extension module

The product also features a single 1-Wire bus for reading data from various 1-Wire sensors (thermometers, humidity meters, light intensity meters etc.). The bus usually utilizes 2-3 conductors and its maximum length can reach up to 200 meters. Up to 15 sensors can be connected to a single bus. 

Software options

Due to the software openness of Unipi controllers the customer has a wide array of software solutions to choose from and is not limited to a single software.

The main supported platform for programming of Unipi controllers is the Mervis system. Mervis is developed according to the IEC 61131-3 standard for PLC programming and consists of SCADA interface for remote control and monitoring, comprehensible development interface, integrated HMI editor and online/on-premise database for storing data and historical analysis of the controlled technology's operation.

Aside from Mervis, Unipi controllers are also compatible with a wide variety of both commercial and open-source platforms. It is also possible to choose from a large number of open-source platforms, use EVOK API, or implement your own code in any programming language.
