These DMG can increase their features with the use of the following expansion modules and satisfy the many diverse needs of Customers. They include:

• Digital inputs and outputs, static and relay type

• Analogue inputs and outputs• RS485, Ethernet and Profibus-DP

interface communications• Data storage with clock calendar (RTC)

for events and data logging• Data storage with clock calendar (RTC) for

events, data logging with Energy Quality.

Multifunction analogue inputs and outputs

The programmable analogue outputs can be configured in voltage or current.

Ethernet gateway function

It allows to read data from group of DMGs connected together in a RS485 network, using one Ethernet port.

Storage module with clock calendar

It provides for data logging of the measurement trends and storing events and alarms with time stamp.

Energy Quality (EN 911131) module

It permits to control the energy quality to EN 911131 normative, storing events (micro breakings, voltage dips, etc.) with time stamp.

These expansion modules are common to all the flush-mount models. The fitting on the multimeters is done with no need of tools and the connection is made with plug-in connectors.

More than 20 partial energy meters, clearable.

• Rated current input /5A• Current connection by CT• Backlight LCD screen (128x80 pixels)• Active energy measurement (Class 1)• Multi-measurements• 3 function keys• Tariff selection input (2 tariffs)• 2 programmable static outputs• Expandable with EXM... modules• 4-module housing

The interface between the DME 912312 and expansion modules is obtained by infrared beam. Appropriate connectors provide for a secure fixing of the expansion modules on the energy meter.

The digital energy meter is made to DIN standards. The width is just 4 modules.

Up to 3 EXM... expansion modules can be fitted on a DME 912312 and permit to:• Communicate• Control alarms, pulses and tariffs• Event storage with time stamp

• Active energy measurement accuracy Class 1 per IEC/EN 62053-21

• Reactive energy measurements accuracy Class 2 per IEC/EN 62053-23

The energy meters are duly equipped with a set of two sealable terminal covers.

Consumption and tariffs (kWh) can be monitored with the digital input for instance , considering different day and night time frames.

The DME 912312 type energy meter can integrate additional functions by using the following modules:• Digital inputs and outputs

The EXM 910113 type expansion module permits the DME 912312 energy meter to be connected to a normal internet network and be viewed, in this way, by one or more connected computers online.

Being equipped with sealable switches, the models can have set-up and clearing locks.To avoid connection tampering, sealable terminal covers are also included.

Type of connections:

• Single-phase• Two-phase• Three-phase with or without neutral• Three-phase without neutral,

ARON connection• Balanced three-phase, with or without neutral.

Type of connections:

• Single-phase• Two-phase• Two-phase with neutral, measurement of

neutral current and neutral-earth voltage.• Three-phase with or without neutral• Three-phase without neutral,

ARON connection• Balanced three-phase, with or without neutral.• Three-phase with neutral, measurements of

neutral current and neutral-earth voltage.

The DMG 910901 can also provide measurements of neutral current and neutral-earth voltage.

DMG 910801 and DMG 910901 types are only 60 mm deep (51.5mm with the terminals covers in place). With the expansion modules mounted, this becomes 80mm.

The mounting on and removal from the panel door are done with no need of tools. A special fixing system provides a quick and immediate operation during both device installation and removal from the panel.
