Industrial I/O module with Modbus RTU/ASCII communication - 8 Digital Inputs and 8 Digital Outputs. Power supply 10-38 V DC; 10-28 V AC

SfAR-S-8DI8DO can be used as a controller’s I/O extension, which, thanks to its unique features, fits a variety of applications, for example, measuring the working time of devices.

The module has 8x digital inputs (DI) and 8x digital outputs (DO). Digital inputs can work as fast pulse counters with up to 1000 counts per sec, or timers measuring the ON state, and also offering a possibility to connect 2 encoders. Digital inputs support both PNP and NPN input types. Digital outputs are PNP transistor outputs. All inputs and outputs are isolated from the logic with opto-isolators.

A built-in RS485 interface allows easy connection over 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/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 connection of up to 10 modules, which provide both RS485 communication and external power supply.
