SFAR-1M-2DI1AO Industrial I/O module

SfAR-1M-2DI2DO is a controller 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 offer the 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.
