The 6SE6440-2UD22-2BA1 HMI is a versatile device that supports a wide range of applications. It comes with a 2-year warranty, ensuring reliability and peace of mind for the users.


The HMI is designed to operate in a three-phase AC power system with a line voltage ranging from 380 to 480 V with a tolerance of ±10%. It supports a line frequency of 47 to 63 Hz, making it compatible with various power supply systems commonly found in industrial settings.

In terms of output, the 6SE6440-2UD22-2BA1 HMI provides three-phase AC output with a rated voltage of 480 V. It delivers a rated power of 2.20 kW or 3.00 hp, with a rated current of 5.90 A in high overload (HO) conditions. The pulse frequency of the device is 4000 Hz, allowing for precise control and operation.

The HMI supports output frequency for V/f (Voltage to frequency) control in the range of 0 to 650 Hz, enabling flexible motor control and speed regulation. This feature is particularly useful in applications that require precise control over motor speed.


With an IP20 degree of protection, the 6SE6440-2UD22-2BA1 HMI offers adequate protection against dust and solid objects, making it suitable for most industrial environments. It is important to note that this HMI should be installed in a suitable enclosure to provide additional protection against moisture and other external elements.


The physical dimensions of the HMI are compact, with a size classified as FSB. It has a net weight of 3.30 kg, making it lightweight and easy to handle during installation and maintenance. The device has a width of 149.0 mm, a height of 202.0 mm, and a depth of 172.0 mm, allowing for flexible installation in space-constrained environments.


The 6SE6440-2UD22-2BA1 HMI offers a range of digital and analog inputs and outputs, enhancing its functionality and versatility. It provides six standard digital inputs, allowing for the connection of various sensors and switches to monitor different aspects of the industrial process. Additionally, it offers three relay outputs, which can be used to control external devices or trigger alarms based on specific conditions.

Furthermore, the HMI features two analog inputs and two analog outputs, enabling the connection of analog sensors or actuators for more precise control and monitoring. This capability is valuable in applications that require continuous measurement and control of analog variables.

The 6SE6440-2UD22-2BA1 HMI also includes a PTC/KTY interface, which allows for connection with temperature sensors such as PTC (Positive Temperature Coefficient) or KTY (Thermistor). This interface facilitates temperature monitoring and control, adding another dimension of functionality to the device.

In conclusion, the Siemens Part Number 6SE6440-2UD22-2BA1 is a feature-rich HMI device designed for industrial automation. With its versatile inputs and outputs, robust construction, and user-friendly interface, this HMI provides an efficient solution for monitoring and controlling processes in various industrial applications.
