Designed for high-precision temperature acquisition within EtherCAT networks, the Beckhoff EL3214 analog input terminal provides direct connection for up to four resistance sensors. This 16-bit resolution module features a highly compact, 12 mm High Density (HD) housing with integrated signal LEDs, saving critical space inside the control cabinet. The terminal dynamically supports both 2-wire and 3-wire connection technologies, ensuring flexible integration with standard RTD sensors including Pt100, Ni100, and various resistance transmitters. Powered directly via the E-bus, it delivers stable, linear measurement results with low noise levels and built-in limit value monitoring.

The EL3214 represents a High Density (HD) upgrade path for installations previously utilizing 2-channel temperature modules like the EL3202. While it significantly increases terminal density (4 channels within a 12 mm width), note that the EtherCAT process image mapping differs. Ensure that the corresponding TwinCAT System Manager configurations are refreshed and PLC variables are remapped when migrating older layouts to the EL3214 structure.
RTD measurements are highly sensitive to self-heating effects. The EL3214 limits its active measuring current to less than 0.5 mA to keep this error margin negligible. However, when placing sensors in stagnant or poorly conductive fluids, small temperature offsets may occur. If electrical grid interference (50 Hz or 60 Hz) affects signal stability, configure the integrated digital filter via CoE (CANopen over EtherCAT) settings to align with your local AC line frequency to achieve optimal noise rejection.
To ensure the rated accuracy of under +/-0.5 degC in 3-wire configurations, all three connection leads must have the identical length, material, and cross-section. Differences in wire resistance between the signal and compensation lines directly introduce systematic offsets. Always use shielded, twisted-pair cabling for long-distance runs and ground the shield immediately at the entry point of the control panel on dedicated grounding rails, ensuring the DIN rail itself has a low-impedance connection to earth ground.
Align the EL3214 terminal with the adjacent EtherCAT module on the standard 35 mm DIN rail (conforming to EN 60715).
Press the module firmly down onto the rail until the side double-slot lock and the bottom DIN rail locking mechanism click into place.
Prepare conductors to a stripping length of 8 to 9 mm. Insert a flathead screwdriver into the spring actuator slot to open the terminal clamp, push the conductor in, and release the tension to secure.
