SFAR-1M-2DI2DO

SfAR-1M-2DI2DO is a controller’s I/O extension, which, thanks to its unique features, fits variety of applications, for example, measuring working time of devices or connecting valves without Modbus support into the Modbus network. The module has 2 digital inputs (DI) and 2 digital outputs (DO). 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. Digital outputs are PNP transistor outputs sending voltage signals. All inputs and outputs are isolated from the logic with opto-isolators. A built-in RS485 interface allows an 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/Os, power supply, and RS485 communication.
