SFAR-1M-4DI

SfAR-1M-4DI is designed for production lines, with options to connect 2 encoders and counting pulses from flowmeters. Perfect choice for applications with a need for counting or timing of digital inputs state. The module has 4 digital inputs (DI). Digital inputs can work as fast pulse counters with up to 1000 counts per sec, or timers measuring the ON state, and also offering a possibility to connect 2 encoders. Digital inputs support both PNP and NPN input types. All inputs and outputs are isolated from the logic with opto-isolators. 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.
