Product Description:

The Beckhoff EL4004 Ethercat terminal is compatible with high-power systems and offers 4 analog outputs. It has four channels and is a part of the EL Ethercat terminals series. It is designed for industrial automation units and works with a 24 V DC power input only. This terminal supplies output voltage within the range of 0 to 10 V and has short-circuit protection for loads less than 5 kOhms. Another important characteristic of this terminal is the usage of the distributed clocks to provide a high resolution of less than one microsecond. This feature helps in maintaining the precise and coordinated output. However, some additional features of the EL4004 include a watchdog facility, which enables the user to set output values as well as the ramp settings to synchronize it according to the user's requirements.

One of the major aspects of the EL4004 terminal is the resolution of up to 12 bits. This implies that any of its output channels is capable of providing 2^12 voltage levels, which range from 0 to 10 V. Analogue signals are filtered at a high resolution, which allows accurate and precise control of motors or any other equipment in the automation industries. Hence, the actual conversion and output time is less than 250 microseconds, with an output error of less than 0.1% from the end value, making the terminal suitable for precise and high-speed control applications.

The EL4004 terminal is suitable to be use in different Industrial areas, especially in outdoor environments or places that offer limited or no control over temperature. This terminal can be used in extreme temperature conditions, such as in very hot and cold climates, due to its strong construction and reliability.
