Product Description:
The ELX3202 is a differential RTD input terminal from Beckhoff that belongs to the EL EtherCAT Terminals series. It installs on the I/O segment of an EtherCAT network to acquire resistance temperature detector signals and forward the converted data to the controller in real time. By integrating two intrinsically safe input channels in a 12 mm housing, the unit allows temperature monitoring inside hazardous zones while its electronics remain on the safe side of the barrier.
The terminal accepts sensor wiring in a two-, three-, or four-wire configuration, so lead resistance compensation can be matched to installation requirements. Internal logic is powered through the E-bus with 5 VDC, while the galvanically isolated field interface is limited to a short-circuit current of 12 mA, an open-circuit voltage of 4.94 V, and a maximum power of 15 mW. These values conform to intrinsic safety energy limits. Each channel draws less than 1 mA of measuring current and follows a linear characteristic curve, preventing self-heating of the sensor element. Two differential inputs are sampled and placed in the process image as two 32-bit RTD values, giving the controller direct access to calculated temperature data without requiring additional conversion.
The module provides a temperature resolution of 0.1 °C per digit and limits total deviation to ±0.3% FS, supporting closed-loop control tasks that require stable accuracy over wide ranges. Field power is supplied through a dedicated contact rated at 24 VDC Ex, so upstream wiring can be fused separately from the logic rail. The IP20 enclosure is suitable for cabinet installation, while support for KT(Y) sensors allows the device to serve mixed RTD installations without additional adapters. Its differential signal acquisition helps reject common-mode interference from nearby electrical equipment, supporting stable temperature readings in industrial machinery. The low measuring current also reduces thermal influence on connected sensor elements during continuous operation.
