Product Description

The Beckhoff EJ3004 plug-in unit is a 4-channel analog input module designed to process voltage signals and transmit them to automation systems. It features a 12-16 pin configuration that serves as an EtherCAT I/O plug-in unit. It is suited for mounting on a signal board , ensuring straightforward connectivity and enhancing system organization. It features a robust build to withstand rigorous conditions, conforming to EN 60068-2-6 and EN 60068-2-27 standards which ensures that the module can withstand conditions with mechanical shocks and vibrations. It also features an IP 20 rating for ingress protection, enhancing its usability in challenging setups for reliable and consistent performance.

The module is equipped with 4 single-ended inputs that allow it to effectively process analog signals from up to four different at the same time. The inputs are suited for -10 to +10 voltage ranges, providing flexibility for various measurement applications. This unit features an integrated E-bus power supply so users do not need to connect it to an additional power source. This keeps installation straightforward and allows ease of integration in different setups. The module’s internal resistance is greater than 130 kΩ, which ensures that signal integrity is maintained for accurate measurements. The signal integrity is further enhanced by the module’s input filter limit frequency of 1 kHz, which helps to eliminate high-frequency noise from the signals.

The EJ3004 plug-in module offers a 12-bit resolution, which allows for precise analog-to-digital conversion of input signals. The data is presented in a 16-bit format, ensuring compatibility with higher-level automation systems. It consumes 120 mA of current, making it efficient in terms of power usage. It offers switchable measuring data representation to adapt to different application needs. It also includes activatable FIR/IIR filter for advanced signal filtering.
