Information About EL3112
The EL3112 is part of Beckhoff’s EtherCAT I/O terminal family, designed for precise analog current measurement in distributed automation systems. It features two differential inputs capable of measuring currents in the 0–20 mA range, supporting high-resolution data acquisition for process monitoring and control. With 16-bit resolution, distributed clocks with <1 µs precision, and fast conversion times down to 35 µs, the EL3112 offers both speed and accuracy for demanding applications. Its advanced features include configurable FIR/IIR filters, compact or standard process image modes, and limit value monitoring, making it suitable for a wide variety of industrial control environments.
Key Features:
-
Dual Analog Inputs: Provides two differential input channels for current signals up to 20 mA.
-
High Resolution: 16-bit signed resolution ensures accurate measurement and fine signal detail.
-
Fast Conversion Time: Supports standard conversion at 50 µs and fast mode at 35 µs for dynamic applications.
-
Advanced Synchronization: Distributed clock support with <1 µs precision enables precise system-wide timing.
-
Flexible Filtering Options: Configurable FIR/IIR filters and 5 kHz input bandwidth improve signal quality.
-
Integrated Safety Features: Limit value monitoring and 35 V surge voltage resistance protect connected systems.
-
Rugged Industrial Design: Electrically isolated up to 500 V between E-bus and signal voltage for secure operation.
-
Compact Form Factor: Slim 12 mm housing with DIN rail installation allows easy integration into control cabinets.
-
Wide Environmental Tolerance: Operates between -25 °C and +60 °C and supports up to 95% humidity without condensation.
-
Low Power Consumption: Draws only 170 mA from the E-bus for efficient system operation.
The EL3112 delivers the reliability and precision required for high-speed, high-accuracy current measurement in EtherCAT-based industrial automation systems.
