It provides four differential input channels that can be individually parameterized for either voltage (±10 V) or current (±20 mA) signals. Featuring 16-bit resolution and distributed clock synchronization, it ensures accurate and time-aligned data acquisition across EtherCAT networks. The terminal includes electrical isolation up to 2500 V between channels and the fieldbus, enhancing system safety and signal integrity. Its ExtendedRange technology and integrated digital filters allow for flexible signal conditioning and noise suppression, making it suitable for dynamic process monitoring and high-accuracy control applications. Key Features: Multifunctional Input Design: Each of the four channels can be individually configured for voltage or current measurement. High-Resolution Measurement: 16-bit conversion provides precise signal acquisition for analog process control. Electrical Isolation: 2500 V functional isolation between channels and bus ensures signal protection and system safety. Fast Conversion: Minimum conversion time of 150 µs for rapid data sampling and process responsiveness. Distributed Clock Support: Enables synchronized, system-wide sampling with microsecond-level accuracy. Programmable Filtering: Integrated FIR/IIR filters enhance measurement stability by reducing noise. Extended Operating Range: Supports voltages and currents beyond nominal values for versatile application use. Compact EtherCAT Integration: 12 mm width saves space while maintaining compatibility with Beckhoff I/O systems. The EL3174-0002 delivers the reliability and precision required for industrial analog measurement, process monitoring, and high-speed automation control systems.
