About the product

SFAR-S-16DI has 16xDI (Digital Inputs). Digital Inputs can work as fast pulse counter up to 1 kHz and support PNP or NPN input types. Every single input is isolated from power supply and RS485 with use of opto- 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 miniUSBallows for initial configuration of the unit without power supply.
To simplify installation the modules have been equipped with Quick Connector system. Using dedicated SFAR-S- LINK cable allows to connect up to 15 modules which provide both RS485 communication and power supply.
