Product description
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 4x 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 easy connection over 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/O, power supply, and RS485 communication.
Configuration of the modules 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 additional power supply.
