SfAR-S-line

The S-Series modules have been specifically developed for industrial automation processes to easily and cost-effectively expand inputs and outputs. Thanks to its built-in LEDs, they provide continuous feedback on operating conditions.

 

The built-in mini USB allows you to quickly configure each module without the need for an additional power supply. This configuration can be done using the free SfAR Configurator. Addressing with DIP switches simplifies and speeds up commissioning.

 

The modules are able to communicate on one of the most popular communication protocols, MODBUS ASCII / RTU.  The IP version of the SfAR-S-ETH module can also be used as a transparent MODBUS TCP / MODBUS RTU or ASCII gateway.

​

Because the modules support the MODBUS protocol, they can be easily applied to both new and existing installations.

​

For even faster installation, the modules are equipped with SfAR-S-LINK connection, which can be used to connect up to 5 or 10 modules. This provides RS485 communication and power supply between the modules, thus reducing cabling costs.
