Beckhoff EL3202 EtherCAT Terminal 2-Channel RTD Input, Pt/Ni/KTY Support, 16-bit, 12×100×68 mm

Overview

The Beckhoff EL3202 is a 2-channel RTD/resistance analog input EtherCAT Terminal for direct connection of resistance sensors. It can output measured resistance in ohms or convert to temperature in the terminal according to selectable sensor characteristics (Pt, Ni, KTY, etc.). Sensors can be connected in 2- or 3-wire technique (default 2‑wire; external bridge required for 2‑wire). Internal digital filtering and limit monitoring are available, and measurement capability/status is indicated by LEDs and process image bits.

Key Features

• Direct connection of RTD/resistance sensors (2- or 3‑wire)
• Temperature conversion in the terminal for Pt100/200/500/1000, Ni100/120/1000, KTY types, and resistance 10 Ω…4 kΩ
• Resolution 0.1 °C per digit; default conversion time ~85 ms (configurable 2…800 ms)
• Temperature ranges: Pt −200…+850 °C; Ni −60…+250 °C
• Galvanic isolation: 500 V (E‑bus/signal)

Applications

• Temperature measurement with Pt/Ni/KTY RTDs in EtherCAT systems
• Direct resistance measurement (e.g., potentiometers)
