GRP-H Single-phase solid state relay with advanced diagnostic, up to 120A



The ability to propose customized control solutions allows to rapidly satisfy the most different automation needs. For this purpose, the GRP series provides a wide range of extremely compact SSRs, with a solid basic structure but scalable as current sizes (from 15A to 120A), control type, and configuration features.


An accurate process control is the condition to achieve a constant and high-quality production. To reach this goal it is necessary to manage in the best way the different types of industrial heaters from linear resistances to infrared lamps. For this purpose, the new series of SSR provides a series of control functionalities (ZC/ /BF/HSC/PA/Softstart) fully configurable to adapt to the various needs.


Preventing possible anomalies allows to limit or eliminate harmful downtime and production. The GRP series includes dedicated functions such as the HB alarm for partial load breakage with an accuracy of 1/8 of the total load, SCR short circuit, overtemperature, and power failure.

IO-Link communication

Factory digitization is reaching its final frontier, the field level of the automation pyramid. At this level, IO-Link is confirming itself as the most suitable communication to easily reach devices such as sensors and actuators. From this perspective, the GRP series has been developed to be integrated within this automation architecture.

NFC configuration

Simple and safe commissioning, maintenance, and quick diagnostics are now within the capabilities of devices like SSR. All this is thanks to the NFC technology, which allows extending the user interface using normal smartphones or tablets as intelligent configurators. Thanks to an intuitive graphical user interface, setup or diagnostics are particularly easy.
