Terminal EtherCAT Beckhoff EL3202-0010

Description

For high-precision temperature measurements in demanding automation architectures, the Beckhoff EL3202-0010 delivers dual-channel analog sensor integration in a highly compact form factor. This EtherCAT Terminal is engineered to handle Resistance Temperature Detectors (RTD) with high resolution and absolute measurement reliability. By utilizing direct 4-wire connection technology, the module effectively eliminates signal degradation and measurement errors caused by long sensor cables, securing accurate process data for feedback control loops.

The unit receives power directly through the standard E-bus connection. Operating with a 16-bit analog-to-digital converter, it provides process temperature values down to a resolution of 0.01 Celsius per digit. An integrated configurable low-pass filter, limit monitoring, and detailed diagnostics ensure that users can tailor the terminal's performance to match specific process dynamics and harsh electrical noise environments.

Features

• Compatible with a wide variety of temperature sensors, including Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, Ni1000, and KTY elements.
• 4-wire connection method for high-accuracy compensation of lead resistance.
• 16-bit digital resolution outputting 0.01 Celsius per digit.
• Configurable conversion times from 2 ms up to 800 ms (default setting: 85 ms).
• Built-in digital filter, limit value monitoring, and integrated diagnostic LEDs.
• Slim 12 mm housing designed for standard 35 mm DIN rail side-by-side terminal configuration.

Applications

• Thermal processing in chemical, petrochemical, and refining facilities.
• Critical cooling and heating loop monitoring in power plants and boiler systems.
• High-accuracy environmental and test chamber monitoring.
• Food processing pasteurization and sterilizing system controls.
