Product description
SfAR-1M-4DI-M is designed for applications with flowmeters, thanks to its counting feature with saving to FRAM memory. 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. SfAR-S-16DI-M comes with a FRAM memory, allowing a user to save states of counters or timers in case of power loss. Digital inputs support both PNP and NPN input types. All inputs are isolated from the RS485 and power supply.
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 to perform a primary configuration of the unit without additional power supply.
