Description
Designed for high-precision temperature sensing in demanding industrial environments, the Beckhoff EL3201-0010 is a 1-channel analog input terminal engineered to interface directly with resistance temperature detectors (RTDs). This EtherCAT terminal utilizes a 4-wire connection methodology, enabling active lead resistance compensation to achieve high measurement accuracy across varying environments.
By digitizing signals with 16-bit resolution, the EL3201-0010 RTD sensor terminal provides highly stable and linearized temperature monitoring. The module comes equipped with integrated digital filtering, limit value monitoring, and configurable conversion rates, making it an essential hardware component for critical thermal management, process monitoring, and calibration systems.
Features
- Single-channel high-precision analog input optimized for Pt100 and other resistance sensors.
- 4-wire connection technology for complete compensation of lead-wire resistance.
- 16-bit resolution with an integrated configurable digital filter.
- Compact 12 mm terminal housing with diagnostic and signal status LEDs.

Installation Guidelines
- Mount directly onto a standard 35 mm DIN rail (conforming to EN 60715) with an integrated lock.
- Ensure stable side-by-side terminal mounting using the double slot and key connection mechanism.
- Verify that the cumulative current consumption of the E-bus does not exceed the power supply limits of the upstream coupler or power terminal.
- Utilize properly shielded cables for analog signal connections to prevent electromagnetic interference.
