1.1 Description of the device
The IE14 single-phase energy meters are intended for energy measurements in single-phase electrical
power networks and can be used in residential, industrial, and utility applications. Meters measure
energy directly in 2-wire networks according to the principle of fast sampling of voltage and current
signals. They are equipped with a capacitive touch button that allows the user to scroll measurements
and the menu, make settings, etc. and backlight for better visibility. A built-in microprocessor
calculates active/reactive/apparent power and energy, current, voltage, frequency, power factor,
power angle, and frequency from the measured signals. This smart meter can also perform basic
harmonic analysis (THDU, THDI). This enables a quick overview of harmonic distortion either coming
from a network or generated by the load.
The microprocessor also controls LCD, LED, IR communication, and optional extensions.
Connecting terminals can be sealed up against non-authorised access with protection covers. They are
built to be fastened according to EN 60715 standard.

1.2 Single-phase energy meters application
Energy meters can be equipped with an optical (IR) communication port on the side as a standard. A
special USB adapter (size 1 DIN module) can easily be attached to it. It can be used for direct
communication with a PC to change settings of the device without any communication installed.
Meter has an optional built-in optical (IR) communication port on the side. It can be used for
controlling Bistable switch –BICOM or in combination with SG smart gateway (more info about BICOM
and SG can be found on https://www.iskra.eu/.
Meter can be equipped:
S0 output (pulse output) is intended for connection to the devices that are checking and
monitoring consumed energy.
RS485(Modbus) serial communication with the Modbus protocol. Data is available in different
formats prepared for easier integration into third party control and monitoring systems.
M-Bus serial communication, which enables data transmission and thus the connection of the
measuring places into the network for the control and management with energy.
NFC communication for easy setting and downloading meter data via a mobile app.
Communication modules enable data transmission and thus the connection of the measuring places
into the network for the control and management with energy.
On the housing there are only two terminals, thus only one functional extension is possible (serial
communication, M-Bus).
NFC communication is implemented for parametrization as well as for reading data (e.g. counters,
measurements, etc) from the smart meter. Special application available from our internet site has to
be used to perform such operations.
Special version IE14MDC with RS485 communication is equipped with a crypto chip and can produce a
relevant digital signature in applications that require additional data security.
