SFAR-1M-2DI1AO

Modbus I/O module with 2 digital inputs and 1 analog output.

Modbus I/O Module
SfAR-1M-2DI1AO is designed for connecting inverters without Modbus support into the Modbus network.

2 Digital Inputs & 1 Analog Output
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 2 encoders. 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 optoisolators.

Simplified Configuration and Commissioning Process
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.
Configuration of the module is carried out with our free software, the SfAR Configurator. A built-in mini USB allows for performing a primary configuration of the unit without an additional power supply.
