Product Description:
The Beckhoff EL3208 EtherCAT Terminal contains 8 incremental sensor inputs to connect multiple sensor devices at once.
E-bus power provides the terminal with its operational power as it integrates itself efficiently into EtherCAT systems. This EL3208 system enables sensor connection for Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, Ni1000, resistance measurements and KTY sensors. The terminal adaptability suits diverse temperature measurement applications because of its flexible design functions. Installation becomes simple because a 2-wire connection enables compatibility with typical industrial sensors. The Pt sensors cover measurement temperatures between -200°C to +850°C, whereas Ni sensors operate between -60°C to +250°C to enable temperature measurements across a wide range. The measuring current of the terminal reaches less than 0.5 mA based on load conditions to reduce power usage without affecting measurement precision. The measurement precision reaches 0.1°C per digit, which makes this device appropriate for essential temperature control operations. The reliability of measured temperatures from the terminal depends on its Pt sensor measurement error of ±0.5°C, which provides readings within this specific tolerance range.
An input filter with a 1 kHz limit frequency provides the terminal with stable and accurate measurements regardless of the environmental noise. The terminal reaches its default conversion time of 170 ms, but programmers can modify this from 3 ms to 1600 ms for various specific applications. The E-bus system utilizes 140 mA of current while running, so the EL3208 serves tasks with continuous energy efficiency. The electronic sensor works between -25°C and +60°C ambient temperatures and includes IP20 protection to protect against dust while preventing accidental contact. The terminal has ±30 V overvoltage protection for signal inputs, so external voltage spikes won't interfere with its functionality.
