Overview
The Beckhoff EL3208 is a high‑density EtherCAT Terminal that connects up to eight resistance sensors (RTDs/resistors) within just 12 mm width. It converts resistance directly to ohms or to temperature in the terminal according to selected sensor characteristics (Pt, Ni, KTY). Sensors are connected in 2‑wire technique. Measurement capability/status is indicated via LEDs and process image bits.
Key Features
- 8 RTD/resistance inputs in a 12 mm HD housing
- Supported sensors: Pt100/200/500/1000; Ni100/120/1000; KTY types; resistance 10 Ω…4 kΩ
- 2‑wire connection method
- Resolution: 0.1 °C per digit
- Default conversion time ~170 ms (configurable 3…1600 ms)
- Measurement ranges: Pt −200…+850 °C; Ni −60…+250 °C
- Input filter limit frequency: typ. 1 kHz
- Galvanic isolation: 500 V (E‑bus/signal)
Applications
- Multi‑point temperature monitoring with Pt/Ni/KTY RTDs
- Direct resistance measurement (e.g., potentiometers) with temperature conversion
