SfAR-S

Slim Modbus I/O Modules
The S line consists of slim modules offering 6-16 inputs and outputs in 12 combinations. Each module is equipped with an optoisolator between the inputs/outputs, power supply, and RS485.

Open Communication Protocols
Each SfAR I/O module has the Modbus RTU/ASCII onboard supporting up to 128 modules on the RS485 bus. There is also a possibility to integrate them into a Modbus TCP/IP network thanks to the dedicated SfAR-S-ETH module.

Quick Connector System
To simplify an installation, the modules have been equipped with the Quick Connector system. Using a dedicated SfAR-S-LINK cable allows for connecting of up to 10 modules.

SfAR-1M

The Smallest Distributed I/O Modules
The 1M line consists of small modules with a small amount of I/Os – 7 types of modules with 2 to 4 I/O’s. Each module is equipped with opto-isolation between I/O’s, power supply, and RS485 onboard is a perfect choice for distributed systems with devices scattered over a large area.

Made to Control and Communicate
Each module in this line is created for specific purpose with a main goal – to connect devices without Modbus onboard into the Modbus network.

Simple Configuration and Commissioning
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 modules 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.
