SFAR-1M-4DI-M

SFAR-1M-4DI-MAbout the product SFAR 1M 4DI has 4x DI (Digital Inputs). Digital Inputs can work as fast pulse counter up to 1 kHz with save to FRAM memory, support PNP or NPN input types. All inputs are separated from power supply and RS485 block with use of optical isolators. Built in RS485 interface allows to easy connection over Modbus RTU ASCII protocol with a PLC makes the modules an external I O. The use of 32 bit ARM core processor provides fast processing

About the product

SFAR-1M-4DI has 4x DI (Digital Inputs). Digital Inputs can work as fast pulse counter up to 1 kHz with save to FRAM memory, support PNP or NPN input types. All inputs are separated from power supply and RS485 block with use of optical isolators.
Built-in RS485 interface allows to easy connection over Modbus RTU/ASCII protocol with a PLC makes the modules an external I/O. The use of 32-bit ARM core processor provides fast processing and communication with the baud rate from 2400 to 115200 bps. The module is equipped with a set of LEDs used to indicate the status of inputs, power supply and RS485 communication. This feature is useful for diagnostic purposes and helping to find errors.
Built-in mini USB allows for initial configuration of the unit without power supply.
