DMM3 LON
The energy analysis comes into the LONWORKS world

DMM3-LON

The leading technology for the building and factoring automation is now available in this Energy Analyser from Elcontrol Energy Net.
This unique instrument can be connected to any LONWORKS system, ensuring the full compatibility.
It is equipped with a standard communication interface that transmits several measures
The transceivers available are FTT10 and RS485.

The instrument is derived from the high quality series VIP 39din, with an improved
accuracy and additional measures on the display.

It features an extremely bright LED display, 3 years-warranty period, 28 true RMS measures, calibration certificate

WHAT IS LONWORKS

LonWorks is a universal control-networking platform that allows you to inexpensively implement a reliable distributed control network. A LonWorks network is made up of intelligent devices (nodes) that can sense, process, communicate, and control a multitude of applications ranging from handheld instruments to large process control systems.

LonWorks was introduced in 1991 and is supported by more than 4000 companies worldwide. The technology incorporates all the necessary hardware and firmware functions needed to implement a complete control network solution dedicated to performing both network and application tasks. Neuron chips, manufactured by multiple vendors, form the heart of most LonWorks nodes. As a semi-dedicated family of microcontrollers, Neurons have programmable I/O lines and memory interfaces and are capable of performing the same functions as a microcontroller. The key difference is that Neuron chips are also able to communicate with each other via the LonTalk protocol and an external transceiver, allowing the creation of networks with as little as 2 devices to as many as 32,000.

TRADITIONAL SYSTEM: PLC or PC required !

LONWORKS SYSTEM: HMI interface optional !!

LonWorks control applications are being created for OEMs and end users within the Semiconductor, Industrial Automation, Building Automation and Home/Utility Automation industries.

TRANSCEIVERS and MODELS

1) DMM3 LON FTT10
FTT-10A Free Topology Twisted Pair Transceiver supports polarity-insensitive star, bus, and loop wiring, freeing the system installer from the need to wire using a bus topology. Free topology wiring reduces the time and expense of system installation by allowing the wiring to be installed in the most expeditious manner. It also simplifies network expansion by eliminating restrictions on wire routing, splicing, and node placement.

2) DMM3 LON RS485
The RS485 twisted pair is one of the most popular transmission media. This model allow the direct connection of the DMM3 in such kind of applications.


Any other type of transmission media requires the utilization of a gateway

OUTPUT

One digital output for alarm or pulses.
T
he alarm setup includes the association of the measure, thresholds, hysteresys % and delay time. The pulses mode allows the setting of the measure, the number of pulses per unit , the pulse width 100 msec or 20 msec.
