Product Description:

The ELM3702-0000 operates with a differential signal type, ensuring accurate signal measurement and processing for a wide range of industrial applications. It is a Beckhoff terminal that is engineered to provide high performance, with a resolution of 24 bits, enabling precise data acquisition for critical control processes. It features two channels that facilitate real-time data collection from different sources. This capacity enhances operational efficiency and flexibility, allowing users to monitor various parameters concurrently. The terminal supports a broad spectrum of input configurations, accommodating various sensor types and signal formats. This versatility offers adaptability to various application demands.

The terminal features a maximum sampling rate of 10 ksps per channel, making it suitable for dynamic processes that require real-time monitoring and control. It boasts an internal resistance greater than 500 kΩ for 60 V inputs and greater than 4 MΩ for other inputs. This ensures measurement accuracy by limiting the effects of loading on the connected sensors. This high internal resistance also helps protect sensitive input signals from voltage drops and signal degradation. Users can easily monitor and troubleshoot system performance via the integrated diagnostics that enhance usability and ensure system reliability.

The ELM3702-0000 features distributed clocks functionality with an accuracy of less than 1 µs that ensures synchronized operation of multiple terminals in the EtherCAT network. It has a typical consumption of 530 mA from the E-bus. The terminal has a thermal dissipation of approximately 3 W, ensuring that it operates without generating excessive heat. This maintains the reliability and longevity of the device. It measures 30 mm x 100 mm x 95 mm and accommodates installation on standard DIN rails making integration simple.
