Overview

Function modules for SIRIUS 3RF2 solid-state switching devices

A great variety of applications demand an expanded range of

functionality. With our function modules, these requirements can

be met really easily. The modules are mounted simply by click-

ing them into place; straight away the necessary connections

are made with the solid-state relay or contactor.

The plug-in connection to control the solid-state switching de-

vices can simply remain in use. The external connections have

screw terminals.

The following function modules are available:

• Converters

• Load monitoring

• Heating current monitoring

• Power controllers

• Power regulators

With the exception of the converter, the function modules can be

used only with single-phase solid-state switching devices.

Recommended assignment of the function modules to the 3RF21 single-phase solid-state relays

The use of power controllers/regulators is also possible on zero-point

switching versions for full-wave control mode. The generalized phase con-

trol mode is recommended only for the combination with instantaneous

switching versions.
