UniPi Axon S215 programmable logic controller (PLC) features I/O architecture combining digital inputs and relay outputs while retaining compact 4 DIN dimensions. The S215 is a variant of the S205 model with 1-Wire bus being replaced by a single RS232 serial line.
The I/O architecture of the UniPi Axon S215 model is focused on a higher number of digital inputs and relay outputs. Thanks to 8 digital inputs and 8 relay outputs, the S215 can offer an I/O number comparable with larger units while retaining compact dimensions. That makes the S215 especially suitable for smaller automation tasks. In contrast to the S205 model, the S215 has the 1-Wire bus replaced by an RS232 line, making the unit suitable for connection of various third-party devices
8 digital inputs (DI) are designed for reading logical states (true or false), which are represented by levels of DC voltage. That makes them suitable for reading two-state sensors such as switches (on/off), movement sensors (movement/no movement), water level sensors (water present, no water) etc. The software detects logical 1 (true) if the input voltage between given DIx.y and DIGND is between 5-35V. If the voltage is lower than 3.5V, the state is evaluated as 0 (false)
8 relay outputs are used for control or switching of devices with higher current loads. ROs are thus suitable for controlling light bulbs, thermoelectric valve drives, water heaters, pumps etc. Relay outputs on UniPi controllers are rated for 5A max. current at 230V AC/30V DC voltage.
The unit features a single RS485 serial line. This type of serial line most often uses the Modbus RTU protocol. It can be used for communication with a wide variety of devices such as energy meters, touchscreen HMI panels, PLCs from other vendors or our Neuron xS extension modules. The bus can communicate with up to 32 devices with its total length being up to several hundred meters.
The controller also features a single RS232 serial line for communication between two devices. In automation, it is most often used for communication with HMI displays, various gateways or closed technologies.
For network communication, a single 1Gbit Ethernet is provided.
Customers can choose from a wide variety of software solutions thanks to the open nature of Axon controllers and are not limited to a single platform. Available are both professional and open-source solutions.
Our main supported solution for UniPi controllers is the Mervis. This platform is developed in accordance with IEC 61131-3 PLC programming standard and contaiíns SCADA interface for remote management and monitoring, comprehensible development environment, user interface (HMI) editor and online/on-premise database for data storage and retrospective operation analysis of monitored technologies.
Aside from commercial platforms, several open-source solutions are available as well. Alternatively, customers can use their own code or implement Axons into already existing software solutions through the use of EVOK open-source API.
