Engineered and manufactured in Italy Pensato. progettato e prodotto in Italia The Lyra devices, in their elegant and functional container, are the ideal solution for applications of measurement, monitoring and management of energy and environmental carriers in the commercial and residential sector. The Lyra series can be used also for remote control, alarm management, building automation, and similar applications. [Lyjjpa (Fgmly Lyra ECT Net H is an Energy Analyzer & Wi-Fi Web Data Manager (also battery powered) for the measurement of electrical parameters in Low Voltage and the logging of various other energy carriers . The device also measures individual harmonics up to the 51st order. It is compliant exclusively with Electrex ECT Current Transformers. It is equipped with connectors for connections to the Ethernet network, for the Electrex environmental sensors and in order to connect the Lyra ECT RS485 Two Energy Analyzer and / or the Lyra I-O and / or other RS485 Modbus RTU devices to the RS485 network. Lyra ECT RS485 Two Energy Analyzer contains 2 x three/single-phase measuring instruments (that use exclusively the Electrex ECT Current Transformers and must be connected in an RS485 network to a device of the Net families). Lyra I-O consists of digital and / or analog inputs and / or outputs and must be connected in an RS485 network to a device of the Net family. Lyra ECT Net_ overvoltage, using Modbus-RTU, master type, allowing to connect other Electrex devices in a sub-network. Astronomical Clock Calendar_ Lyra ECT Net is equipped with a clock/calendar with astronomical real time management of the Coordinated Universal Time (UTC). It manages also the rules for the automatic switching from Standard Time at summer time (Daylight Saving Time) and vice versa. Automatic synchronization via NTP. Example of a monitoring system including Lyra_ H is equipped with a FSTN dot matrix display with high contrast, back lighted, white LEDs allowing the simultaneous displaying of 4 measurements and of their identification symbol with high visibility characters. The 6 keys keypad Joystick positioned and menu list type on the display for configuration provide a simple and rational use of the instrument, while the default page displayed when powering on is user definable. On the front panel 2 calibration and control LEDs pulse with a frequency proportional to the imported Active and Reactive Energy for the on-field calibration with optical devices. In order to reduce the energy consumption it is possible to configure the display's back-lighting. Versatility of the Lyra ECT Net H (Wi-Fi)_ The Lyra ECT Net H are suitable for LV, single phase systems (from 1 to 3 simultaneous measuring points), bi-phase, three phase 3- and 4-wires with various current full scales (e.g. up to 400A). 2 or 4 quadrant (import/export) measurement. Configuration from the keyboard (and/or via Energy Brain software. The Lyra ECT Net H is also available in the version (can be powered at 12Vdc) with a back-up battery to keep the microprocessor and any temperature, humidity and light sensors connected to it active in the event of power failures. The Wi-Fi version communicates with the existing Wi-Fi network and is equipped with an external directional antenna. The device can include a digital and/or analog inputs and/or outputs board or an environmental sensors connection board. Ethernet communication and Rs485 sub-network Lyra ECT Net H is equipped with a 10/100 Base-TX (RJ45) Auto-MDIX Ethernet port for the “http” communications (realtime measurements and memory logs) and “Modbus over IP”. It is equipped also with a serial RS485 port, protected against DECA SENSOR DECA SENSOR DECA SENSOR In the example above the Lyra ECT Net H SI monitors the general consumption of the building and acts as a datalogger for some devices connected in the RS485 subnet and other devices connected to the internal SI board (I2C bus). In the RS485 subnet there is the Deca Coordinator E-Wi which communicates, via Radio at 868MHz, with the two Deca Sensor E-Wi 868 TH which measure temperature and relative humidity in various rooms; there are also the RS485 Node connected to a Sensor Bus Unit TH and a Deca Sensor RS485 for other measures of environmental parameters. Connected directly to the SI board (I2C bus) there are also other Sensor Bus Units TH.

Engineered and manufactured in Italy Pensato. progettato e prodotto in Italia Lyra ECT RS485 Two Energy Analyzer_ The Lyra ECT RS485 Two Energy Analyzer contains two three/single-phase transducers/analyzers (using exclusively the Electrex ECT Current Transformers) and must be connected to a Net device in an RS485 network. It is available in different versions depending on the type of the internal boards (maximum two) of digital and/or analog inputs and/or outputs of which it can be equipped. Thus, in addition to the measurements of electrical and energy parameters, also pulses can be counted...
