About the product
SFAR-1M-2DI1AO has 2x DI (Digital Inputs) and 1x AO (Analog Output). Digital Inputs can work as fast pulse counter up to 1 kHz and support both PNP or NPN input types. Analog Output can work as 0-10 V DC or 0-20 mA output with 12-bit DAC support. All inputs and output are separated from power supply and RS485 block with use of optical isolators. Built-in RS485 interface allows to easy connection over Modbus RTU/ASCII protocol with a PLC makes the modules an external I/O.
The use of32-bit ARMcore processor provides fast processing and communication with the baud rate from 2400 to 115200 bps. The module is equipped with a set of LEDs used to indicate the status of inputs, outputs, power supply and RS485 communication. This feature is useful for diagnostic purposes and helping to find errors. Built-in mini USB allows for initial configuration of the unit without power supply.
