The UniPi Axon S105 is a programmable logic controller (PLC) designed for control, monitoring and management. The S105 represents the most universal model in the entire UniPi Axon product line, combining broad functionality with small dimensions.
UniPi Axon S105
- most versatile Axon variant
- small combination, 10 I / O and three serial lines (RS485 + RS232)
- cDurable aluminum hassi (IP20 protection), wider operating temperature range
- integrated industrial computer (quad-core CPU, 1 GB RAM)
- 8GB integrated eMMC memory
- designed for DIN rail mounting
- management software (based on Linux OS)
- Mervis software preinstalled (can be updated again)
UniPi Axon S105 is a universal PLC featuring all necessary I / O modules and communication interfaces except for relay outputs. It comes with digital and analog I / O's, 1-Wire bus, RS232 and RS485 buses while retaining its compact dimensions. That makes the S105 suitable for creating new smaller automation systems or easy integration into existing systems.

Inputs & outputs description
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.
Digital Outputs (DI) are intended for switching various binary devices (lighting, smart door locks, drives of shutters and blinds etc.) through direct voltage. DO's also feature Pulse-Width Modulation (PWM) function allowing to use the output for analog control.
Analogue input (AI) is designed to measure voltage, current or resistance to read values from various analog sensors such as thermometers, pressure meters, tensometers etc.
Analogue output (AO) serves for control of multi-state external devices through direct voltage or current and is suitable for control and regulation of devices such as three-way valves, heat exchangers, electric motors etc.
As a computing module, the Axon controllers use an industrial computer featuring a quad-core 1.2GHz Alwinner H5 CPU and 1GB RAM giving Axons an excellent performance. The 8GB onboard eMMC memory offers better reliability compared to systems relying on microSD memory cards.
Axon controllers are by default provided with RS485 serial lines. This type of interface usually uses the Modbus RTU protocol and can be used to communicate with various devices such as Extension xS extension modules, energy meters, touchscreen HMI displays, controllers from other vendors, various sensors etc. A single bus can support dozens of devices while the bus can reach up to several hundred meters.
Selected models also feature a single RS232 serial line. In the field of automation, this interface is usually used for communication with various converters, closed-in technologies or display devices such as HMI panels.
A single 1-Wire bus is also featured on selected models. This interface uses 2-3 conductors for collecting data from various 1-Wire sensors such as thermometers, humidity meters, light intensity sensors etc.). The single 1-Wire bus supports up to 15 devices, the overall length of the bus can reach up to 100 meters.
All Axon models also feature a single 1Gbit Ethernet byt for network communication.
Thanks to the openness software of Unipi controllers customers can choose from a wide range of software solutions and are not limited to a single proprietary platform. Among supported solutions are both commercial and open-source systems.
The main supported platform for Unipi controllers is the Mervis control system. This platform is developed under the IEC 61131-3 PLC programming standard and consists of comprehensible and user-friendly Mervis IDE development environment, an HMI editor for creating and editing of user interfaces, SCADA interface and an online / on-premise cloud database for long -term collecting of operational data and their analysis. Axon-line controllers are shipped with the Mervis already installed.
Aside from commercial platforms (such as CODESYS), customers can also choose from a variety of open-source solutions; for the supported software overview please visit this link.
Alternatively, customers can use the Unipi-developed EVOK open-source API to integrate Unipi controllers into existing software solutions, use custom code or to develop applications for the controllers.
All components of the controller are encased within a durable aluminum chassis (IP20 protection). The controller is designed for mounting on a standard DIN rail (35 mm).
