Here’s a concise breakdown of the Beckhoff EL3201 EtherCAT Terminal:

• Functionality: 1-channel analog input terminal designed for temperature measurement using RTD sensors (e.g., Pt100, Pt1000, Ni1000, KTY types).

• Measurement Output: Can provide resistance values directly or convert them into temperature readings.

• Sensor Compatibility: Supports 2-, 3-, and 4-wire connections (default: 2-wire; external bridge needed for 2-wire setup).

• Resolution & Accuracy: Offers 16-bit resolution with a measurement error of < ±0.5°C for Pt sensors.

• Temperature Range: -200°C to +850°C for Pt sensors; -60°C to +250°C for Ni sensors.

• Electrical Isolation: 500V (E-bus/signal voltage).

• Special Features: Integrated digital filter, limit value monitoring, and variable connection technology.

• Installation & Build: Compact DIN rail mountable terminal with IP20 protection rating.

• Certifications: CE, CCC, UL, ATEX, IECEx
