Product Description:

The Beckhoff EL302 is a versatile analog input terminal designed for precise measurement of output signals in industrial automation systems. This analog terminal has two differential inputs with the standard signal current of 4 to 20 mA. These signals can be used to run sensors and many industrial control systems to send information in analogue forms related to temperature, pressure or flow rate. The 12-bit signal is provided as a 16-bit signal to offer better accuracy. It operates effectively within a wide temperature range of -25 to +60 degrees C, making it suitable for challenging environmental conditions.

Some of the technical characteristics of the EL3022 include a sample conversion time of 0.625 ms, which enables it to collect data promptly. It has an input filter limit frequency of 1 kHz, which helps in eliminating any interference in the input waveform by providing accurate measurements. The terminal is also equipped with surge voltage resistance of up to 35 V, providing additional protection against voltage spikes and shocks, by improving its reliability. This terminal has around 85 ohms plus diode voltage and is optimized for providing continuous current signals. The power is supplied by the E-bus, and the consumption is about 130 mA, which makes it flexible for connection with Ethercat systems.

It is used for applications related to industrial processes, monitoring and automation where a high degree of current measurement accuracy is necessary. The input is differential to reduce interferences and noises, while its common mode voltage is 10 V. The EL3022 is ideal for use in machinery or building systems where a high accuracy, speed, and safety of the current signal input is required.
