Product Description:

The Beckhoff EP3204-0002 digital input module delivers highly precise and versatile temperature measurement for industrial applications. As part of Beckhoff's reputable EP Digital Input Series, this device supports four measurement inputs and operates on the open EtherCAT communication standard. It accommodates a wide variety of common temperature sensor types including Pt100, Pt200, Ni100, and resistance-based elements, offering adaptable solutions. Particularly suited for tasks like process monitoring and HVAC/R system oversight, the EP3204-0002 determines temperatures over an extensive range from -200°C to +850°C.

Resolution of 0.1°C per digit paired with measurement accuracy under ±0.5°C for Pt sensors in a 4-wire setup ensures reliable and repeatable readings. Open-circuit detection adds an important safety feature, alerting to potential sensor faults. Hardware filters allow smoothing readings as needed by application. User-configurable settings afford flexible adjustment to optimize performance. Operation continues unaffected even in challenging electrical environments thanks to integrated shielding and intrinsic noise immunity with EtherCAT digital communication. A stable 24V power supply feed—with overvoltage and reverse polarity protection—further reinforces robustness.

Mounting conveniences like DIN-rail attachment and space-saving 126mm wide housing promote seamless integration into control cabinet architectures. M12 connection ports facilitate simple and secure wiring while withstanding mechanical strains. At just 120mA current draw, several modules may operate simultaneously from a single power supply. On-board parameterization via TwinCAT software permits thorough calibration and adjustments from a single computer interface. Comprehensive diagnostic functionality enables predictive maintenance through early issue detection.
