EL3314-0000 by Beckhoff

The EL3314-0000 terminal from Beckhoff is part of the EL EtherCAT Terminals series and is engineered for precise temperature measurement and reliable signal acquisition. This terminal is designed to acquire four input channels with a high degree of accuracy using a 2-wire connection method and a 16-bit, adjustable representation resolution. It is ideally suited for applications involving thermocouple-based temperature measurements, where real-time monitoring and detailed analysis are critical.

Detailed technical specifications include a conversion time ranging from approximately 2.5 s up to 20 ms (with a default around 250 ms), and a typical E-bus current consumption of 200 mA, which ensures consistent and efficient operation. It also supports input filter frequencies up to 1 kHz and provides voltage measurement within limits of -30/-60/-75 mV. The terminal is designed with measurement uncertainties for temperature between +/-2.5°C and +/-8.5°C depending on the type, and voltage uncertainty of less than +/-0.14% at 75 mV, enhancing the reliability of the readings.

Additional features of the EL3314-0000 include channel by channel wire break detection, which allows for monitoring the integrity of each input signal, and compatibility with a wide range of thermocouple types including B, C, E, J, K, L, N, R, S, T, and U (with K as default). Moreover, it complies with standards for vibration and shock resistance (EN 60068-2-6/EN 60068-2-27), and its design supports efficient integration in control cabinets due to its compact dimensions and DIN rail mounting. Benefits include enhanced durability, streamlined wiring, and robust operation in industrial settings, making it a reliable choice for automation projects.
