SFAR-S-16DI-M

SfAR-S-16DI-M is a controller’s I/O extension, which, thanks to its unique features, fits a variety of applications, for example, counting pulse signals from flowmeters. The module has 16 digital inputs (DI). Digital inputs can work as fast pulse counters with up to 1000 counts per second, or timers measuring the ON state and offering a possibility to connect 2 encoders. The SfAR-S-16DI-M module comes with a FRAM memory, allowing a user to save states of counters or timers in case of power loss. Digital inputs support both PNP and NPN input types. All inputs are isolated from the RS485 and power supply. 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 an external power supply.
