Description
The 80 A three-phase compact energy meter Ekinex® EK-ME1-80T performs the
measurement of energy and main electrical parameters in industrial and civilian
application. The backlighted LCD allows to display energies and instantaneous
powers. Delivery includes a tariff input and two S0 outputs for energy pulse
emission. The device is also equipped with an optical port for communication with
other systems as well as Ekinex® Modbus RS485 (EK-MC1-MD) and KNX (EK-MC1-
TP) communication modules. It has MID certification for billing, metrological LED on
the front panel and lateral anti-effraction sealing. The device is suitable for mounting
on a 35 mm DIN rail.

EK-ME1-80T
Description
The Ekinex® RS485 Modbus communication module EK-MC1-MD collects and
transmits, through Modbus RTU or ASCII protocol, measurement data of Ekinex®
single and three phase energy meters. Data transmission between meter and
communication module is performed through the integrated optical port. Change of
RS485 parameters is made directly on the combined meter or by sending the proper
Modbus protocol commands to the module. The device is suitable for mounting on a
35 mm DIN rail.
Main features
• Plastic casing
• Set default pushbutton to restore all parameters to the factory settings
• Frontal LED for Power (POWER) and Communication (ACT / ERR) status
• Bus line connection through KNX terminal block
• Installation on 35 mm DIN rail (according to EN 60715)
• 1 modular unit (1 MU = 18 mm)
• Protection degree IP20 (installed device)
• Weight 65 g
