This multi-function terminal features electrically isolated differential inputs, allowing each channel to be individually parameterised through the control system to process either current or voltage signals. The exceptional 2500 V functional isolation between channels and to the fieldbus makes it an ideal choice for preventing ground loop problems and ensuring high signal integrity in complex electrical environments.\u003c\/p\u003e\n\u003cp\u003eAs part of the modular BECKHOFF EtherCAT I\/O system, the \u003cstrong\u003eEL3174-0002\u003c\/strong\u003e integrates directly into standard terminal segments. It operates with 16-bit resolution and supports Distributed Clocks (DC) for precise synchronization of measurements across the entire control network. The combination of flexible parameterization, electrical isolation, and high-speed EtherCAT communication provides reliable data acquisition for demanding test, measurement, and control systems.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eFour analog input channels, with each channel individually parameterizable for voltage or current
