Yaskawa's SI-N1 is a communication interface designed specifically for DeviceNet use within their Sigma 5 product line. It provides robust support for various I/O message types, including Basic, Expansion, Modbus, and Standard Drive Control, allowing for flexible integration in industrial systems.

Data transfer capabilities include a maximum of 32 bytes per cycle. The unit is compatible with the DeviceNet AC/DC Drive Profile, ensuring efficient management of drive communications. In terms of power requirements, the SI-N1 needs a communication power supply within the range of 11V to 25V DC and draws a very low current of 20 mA or less. The operational power supply, sourced from the connected drive, operates between 4.75V and 5.25V DC.

Regarding environmental specifications, this interface functions optimally in temperatures ranging from -10°C to +45°C, with a humidity tolerance of up to 95% relative humidity (non-condensing). It is intended for indoor applications, as it avoids exposure to corrosive gases and dust particles. Furthermore, it can operate at altitudes of up to 1000 meters above sea level and has a storage temperature range from -20°C to +60°C. The SI-N1 also consumes a current of 100mA for efficient operation.
