Product Description:
The EL3202-0010 EtherCAT Terminal is a compact, high-precision input terminal for direct connection of resistance temperature detectors (RTDs) via Pt-type sensors. This terminal is manufactured by Beckhoff, and it has IP20 protection. This input terminal has a wide range of temperature measurement capability from -200°C up to +320°C, thus facilitating precise monitoring of temperature across diverse industrial settings.
This terminal operates with a 4-wire connecting scheme and provides lead-resistance compensation that enhances measurement accuracy at long distances. With two separate 32-bit RTD input channels, the EL3202-0010 terminal offers accurate and simultaneous temperature acquisition for multiple sensor points. With a high measurement resolution of 0.01°C per digit, this input terminal allows detection of even minute changes in temperature, which is essential for process control and quality monitoring in sensitive applications. To provide signal clarity, this terminal has an input filter with a typical limit frequency of 1 kHz that eliminates high-frequency electrical noise and enhances the stability of the signal in challenging environments. This terminal provides robust system protection with 500 V electrical isolation between the signal voltage and the E-bus to prevent interference or damage from voltage surges.
The housing of this terminal is constructed of rugged polycarbonate material and is small in size, with measurements of 12 mm (W) x 100 mm (H) x 68 mm (D). Each input channel draws a measuring current of less than 0.5 mA, depending on the load characteristics of the connected sensor, to help in maintaining sensor integrity over time. Weighing around 60 g, this input terminal is suitable for standard DIN rail mounting. The EL3202-0010 terminal can operate in environments with -25°C to +60°C temperature range and up to 95% relative humidity, as long as there's no condensation.
Frequently Asked Questions about EL3202-0010:
Q: Why does the EL3202-0010 use a 4-wire connection method?
A: The 4-wire connection eliminates errors caused by lead resistance. This ensures higher accuracy in temperature readings across longer cable runs.
Q: How does the 500 V electrical isolation benefit the EL3202-0010?
A: It protects both the control system and measurement signals from voltage interference. This isolation is crucial in systems prone to electrical noise.
Q: Why is the input filter limit frequency set at 1 kHz?
A: A 1 kHz filter removes high-frequency noise from the analog signal. It ensures stable and clean digital data conversion during processing.
Q: What advantage does the 0.01°C resolution provide in EL3202-0010?
A: It allows detection of small temperature fluctuations in critical applications. This is useful in precision process control environments like lab systems.
Q: How does the 2 x 32-bit RTD input improve performance in EL3202-0010?
A: It allows simultaneous, high-resolution measurements on two channels. This helps monitor multiple temperature points with minimal latency.
