Modbus I/O Module
SfAR-S-6RO is designed to be applied wherever it is necessary to switch to 5 A of AC or 10 A of DC.

6 Digital Outputs
The module has 6 relay outputs (RO). Relay outputs are double-throw contact types, offering both normally open (NO) and normally closed (NC) types at the same time.

Simplified Configuration and Commissioning Process
A built-in RS485 interface allows an easy connection over the Modbus RTU/ASCII protocol. A 32-bit ARM core processor provides fast processing and communication.
The module is equipped with a set of LEDs used to indicate the status of I/Os, power supply, and RS485 communication.
Configuration of the module is carried out with our free software, the SfAR Configurator. A built-in mini USB allows for performing a primary configuration of the unit without an additional power supply.
To simplify the installation, the module has been equipped with the Quick Connector system. Using a dedicated SfAR-S-LINK cable allows for connecting up to 10 modules, which provide both RS485 communication and external power supply.
