SfAR-S-8AI2DO is designed to be applied wherever multiple sensors are used. Thanks to 2 digital outputs and a pre-installed logic in the module, it can be used as a PLC I/O extension and as a standalone application controller. The module has 8 analog inputs (AI) and 2 digital outputs (DO). Analog inputs can work in 7 modes as voltage or current inputs. Digital outputs are NPN transistoroutputs. All inputs and outputs are isolated from the logic with optoisolators. 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. The module has been equipped with the Quick Connector system to simplify installation. Using a dedicated SfAR-S-LINK cable allows for connecting up to 10 modules, which provide both RS485 communication and external power supply.
