About the product

SFAR-1M-4DI has 4x DI (Digital Inputs). Digital
Inputs can work as fast pulse counter up to 1 kHz and 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.
