3RF29 Function Modules

Siemens LV 1 · 2006

■ Overview

Converters for SIRIUS SC solid-state switching devices

These modules are used to convert analog drive signals, such

as those output from many temperature controllers for example,

into a pulse-width-modulated digital signal. The connected

solid-state contactors and relays can therefore regulate the

output of a load as a percentage.

■Application

The device is used for conversion from an analog input signal to

an on/off ratio. The function module can only be used in

conjunction with a 3RF21 solid-state relay or a 3RF23 solid-state

contactor.
