Configurable logical module
UNIVERSAL INTERFACES
Description
The configurable logical module Ekinex® EK-LM2-TP is a KNX S-mode device that
can be used to perform logic and data processing functions on data exchanged on the
KNX bus. The device is suitable for mounting in wall box or on 35 mm rail (EN 60715)
with the support EK-SMG-35 included in the delivery. To be used in KNX installations
for home and building automation. The device is powered by the KNX bus line with a
SELV voltage 30 Vdc and does not require auxiliary power.
Main features
• Housing in plastic material
• Wall installation in flush mounting box or, with a mounting support,
on 35 mm rail (according to EN 60715)
• Protection degree IP20 (installed device)
• Classification climatic 3K5 and mechanical 3M2 (according to EN 50491-2)
• Pollution degree 2 (according to IEC 60664-1)
• Weight 20 g
Functions
The device implements independent blocks of the below listed types:
• Logic: Combines a number of boolean inputs according to logic operations.
• Arithmetic: Performs mathematical computations on one or more input values.
• Range: Performs a scaling of the input value to a different range of values,
or a boundary limit.
• Mapping: Translates a set of input values (up to 8 points) to a different set
of output values.
• Conversion: Converts a KNX communication object to another one with a
different KNX data type (DPT).
• Timer: Implements a one-shot (monostable) or freerunning (astable) timer,
with configurable on- and offdelay times.
• Compare: Returns the result of a comparison (equal, larger, smaller etc.)
between two input values
• Multiplexer: Copies the value of one input object to either 1 of N output objects,
or to all objects selected in the output set.
Each function can be configured in different ways by means of parameters in the ETS
application. There are several independent instances available for each type of block,
therefore the device can be used to fulfill many requirements or to solve a large
number of contingencies in the same installation. An additional terminal block allows
the connection of up to 4 dry contacts for simple external inputs.
Power supply
• 30 Vdc power supply by KNX bus
• Current consumption from bus < 10 mA
Delivery
Delivery includes a terminal block for connection to the bus.
Accessories
Support for mounting on a standard 35 mm DIN-rail (code EK-SMG-35) and spring
for snapping on the back of Ekinex® wall-mount devices (code EK-MAR-...) to be
ordered separately.
