Overview

Converters for 3RF2 solid-state switching devices

These modules are used to convert analog control 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 out-

put of a load as a percentage.

■

Application

This function module is used for conversion from an analog input

signal to an on/off ratio. The module can only be used in con-

junction with 3RF21 and 3RF23 single-phase solid-state switch-

ing devices or 3RF22 and 3RF24 three-phase devices. It can be

used on versions with 24 V DC and 24 V AC/DC control supply

voltage.
