Configurable logical module LM2

Code: EK-LM2-TP

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. 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.

An additional terminal block allows the connection of up to 4 dry contacts for simple external inputs.

Implemented Independent Function Blocks

Logic

Combines a number of boolean inputs according to logic operations.

Arithmetic / Math

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 free-running (astable) timer, with configurable on- and off-delay 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.
