Product Description:

The EL3314-0000 terminal offers a versatile solution for acquiring 4-channel analog input signals with a high degree of precision. Designed by Beckhoff, this terminal allows four thermocouples to be connected directly, making it an ideal choice for temperature measurement applications. It can operate thermocouple sensors using the 2-wire technique, which simplifies wiring and installation. This method reduces the number of conductors needed for sensor connections, allowing for easier integration into existing systems and reducing overall installation costs. The terminal is powered via the E-bus, ensuring a reliable and stable power source directly from the connected automation system.

The terminal has a conversion time that ranges from approximately 2.5 seconds to 20 milliseconds, depending on the specific configuration and filter settings used. This flexibility allows users to adjust the conversion time according to their application needs, making the terminal versatile for various processes. The terminal features a 16-bit resolution, enabling it to provide highly accurate temperature measurements. This level of resolution allows for a greater distinction between temperature values, improving the precision of readings from thermocouples connected to the terminal. It has a typical E-bus current consumption of 200 mA.

The EL3314-0000 terminal offers channel-by-channel wire break detection, which allows the terminal to identify and alert users to any faults in the wiring of individual thermocouples. The terminal also incorporates both internal and external cold junction compensation, helping to maintain accuracy. With compact dimensions of 12 mm x 100 mm x 68 mm, this terminal is designed to fit efficiently within control cabinets, ensuring optimal use of space. It is engineered for installation on a 35 mm DIN rail, conforming to EN 60715, which guarantees secure mounting and stability during operation.
