Product information "UniPi Neuron L203"

UniPi Neuron L203 is a programmable logic controller (PLC) designed for control, monitoring and regulation. The L203 represents the basic model of the Neuron L line and features I/O architecture focused on high number of digital inputs and relay outputs. Being an enlarged variant of the M203, it offers 36× DI + 28× RO. 

Features

  • universal architecture with a very high number of I/Os
  • total of 70 I/Os, best cost-to-I/O number ratio
  • durable aluminium chassis (IP20 protection)
  • integrated Raspberry Pi Model 3B computer (quad-core CPU, 1 GB RAM)
  • designed for DIN rail mounting
  • features RS485 serial line for Modbus communication
  • software openness (based on Linux OS)
  • Mervis lifetime license as part of the package

Description

The L203 is a basic model of the Neuron L line, which, compared to Neuron S and Neuron M lines, features more I/O modules and larger dimensions. The L203 is an extended variant of the M203 and as other 200-line models, it is focused on a higher number of digital inputs and analog outputs. That makes the L203 suitable for extensive automation projects.

Inputs & Outputs

36 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 5-30V. If the voltage is lower than 3.5V, the state is evaluated as 0 (false)

4 digital outputs (DO) are used for controlling two-state devices such as lights, door locks, window blinds etc. Digital outputs on our controllers also feature the PWM (Pulse-width modulation) function, enabling a special type of analog control. Outputs are of the NPN type (open collector) and are able to control devices with voltage up to 50V and up to 750mA load current.

28 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.

1 analog input (AI) can be used for 0-10V DC voltage or 0-20mA current measuring, making them suitable for reading values from analog sensors such as temperature sensors, pressure meters, tensometers etc.

1 analog output (AO) features two modes - 0-10V DC voltage or 0-20mA direct current. AI serves for control of devices with analog input, such as three-way valves, lighting dimmers etc.

More detailed info about I/O usage and settings can be found in Neuron technical documentation (see Files tab above)

Communication interfaces

By standard, all Neuron-line controllers feature a single RS485 serial line for communication with external devices or connection of extension modules, most often through 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 Neuron xS series extension modules) using the Modbus RTU protocol. A single RS485 can communicate with up to 32 devices with its total length being up to several hundred meters. The line can be also used as an RS485 gateway for other devices or systems,.

Included is also a single 10/100MBit Ethernet port for network communication and a single 1-Wire bus for connection of various 1-Wire sensors (such as digital thermometers). The 1-Wire bus uses 2 or 3 conductors for communication with simple sensors such as thermometers, humidity meters or light intensity meters. A single bus can communicate with up to 15 sensors with maximum total length of the bus up to 100 meters.

Software options

Customers can choose from a wide variety of software solutions thanks to the open nature of Neuron 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 enviroment, user interface (HMI) editor and online/on-premise database for data archivation and retrospective operation analysis of monitored technologies. 

Neuron controllers are also compatible with the CODESYS professional platform. designed specifically for use in modern industrial automation. At the same time, the platform is made to be as user-friendly and easy to use as possible. CODESYS is in widespread use around the globe with more than 100 000 users from various countries and more than 1000 companies.

Aside from commercial platforms, several open-source solutions are available as well. Alternatively, customers can use their own code or implement Neurons into already existing software solutions through the use of EVOK open-source API.

Other features

All UniPi controllers are able to measure resistance through analog I/Os. Resistance can be measured by either 2-wire or 3-wire method for increased accuracy. Each controller can measure resistance of up to 2kΩ, with some models being able to resistance measure up to 100kΩ. Detailed info about this functionality can be found in Neuron technical documentation. 

All components are encased within a durable anodized aluminium case providing IP20 cover. The unit's size is 12 DIN modules, DIN rail holder is included in the package.
