UniPi 1.1 is an extension board for the Raspberry Pi computer, allowing it to serve as a programmable logic computer (PLC) in applications such as automation, regulation, monitoring, smart home systems, industrial automation and many more. It is a direct predecessor of the Neuron PLC line.. The board can be extended via EMO-R8 extension module, adding another 8 relay outputs. Users can also purchase a DIN rail holder for installation into a distribution box and plastic protective cover.
UniPi 1.1 is compatible with a wide variety of software. For programming the UniPi we recommend either our open source API EVOK. or our advanced node-based control software, Mervis. EVOK is our official open-source application programming interface (API), designed for remote access to our control units. It represents a simple software allowing the user an easy access to hardware without extensive programming. Mervis is then our primary, officially supported software platform for UniPi PLC management. It is an extensive set of tools for advanced monitoring and regulation, developed in accordance with the IEC 61131-3 programming standard.
Digital inputs are designed for the reading of binary values (0/1, on/off, open/closed etc.) and are thus suitable for connecting switches, motion sensors, window or door magnetic locks etc.
Caution: The cable for connection of Raspberry Pi to the UniPi board does not contain wires for digital inputs 13 and 14. To use these inputs, it is necessary to create a custom connection according to this tutorial
Analogue inputs are used to receive either 0-10V voltage or 0-20mA current signals. Alternatively, they can be used for reading data from corresponding sensors, such as resistance thermometers. The user can adjust the input mode via corresponding control software.
The analogue output can be used for control of external devices such as three-way valves or heat exchangers via 0-10V voltage or 0-20mA current signals. Analogue output also allows current or voltage regulation.
Relay outputs are designed for switching two-state devices via alternating or direct voltage. Relays thus can be used to switch boilers, water heaters, electric motors or other stronger relays. Neuron unit relays are designed for 5A maximum current and 250V alternating/30V direct voltage.
