SfAR-1M-2DI1AO

SfAR-1M-2DI1AO is designed for connecting inverters without Modbus support into the Modbus network. The module has 2 digital inputs (DI) and 1 analog output (AO). 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 an encoder. Digital inputs support both PNP and NPN input types.
The analog output can work as 0-10 V DC, 0-20 mA, or 4-20 mA output. All outputs are isolated from the logic with opto-isolators.
A built-in RS485 interface allows an easy connection over the 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.
