Product description
SfAR-S-ETH module is a Modbus TCP to Modbus RTU/ASCII gateway, allowing to connect Modbus RTU/ASCII devices to the Modbus TCP network.
The device has the Ethernet and RS485 interfaces, 4x digital inputs (DI) and 3x relay outputs (RO). Digital inputs can work as fast pulse counters or timers, they support PNP or NPN input types, also offering a possibility to connect an encoder. Relay outputs are normally open (NO) type. All inputs and outputs are isolated from the logic with opto-isolators.
Communication is performed with the Modbus TCP protocol. The 32-bit ARM core processor provides fast processing and communication. The SfAR-S-ETH offers a unique feature, the Device Table, which facilitates communication with devices connected to the RS485 port, making it even faster.
The module is equipped with a set of LEDs used to indicate the status of I/O, 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 additional power supply.
To simplify installation, the modules have been equipped with the Quick Connector system. Using a dedicated SFAR-S-LINK cable allows for connection of up to 10 modules, which provide both RS485 communication and external power supply.
