Product Description:
The Beckhoff's manufactured EL3061 is a high-accuracy analog input terminal that is used for direct connection of single-ended voltage signals. With a focus on accuracy, signal integrity, and space efficiency, this terminal is a reliable solution for voltage signal processing in EtherCAT-based control systems. This terminal has an internal input resistance greater than 130 kΩ to reduce current draw significantly.
This input terminal is appropriate for the measurement of slowly changing signals with high precision because of its 12-bit resolution, which enables 4096 discrete values within the signal range. This terminal has 1 input channel with an input range of 0 to 10 V, which is used for accurate acquisition of standard analog signals utilized in industrial automation. No separate power supply is needed for the EL3061 input terminal, since it is supplied with operating power directly through the E-bus. This minimizes cabling complexity and ensures synchronous communication. This terminal features an input filter with a frequency limit of 1 kHz, which has the effect of filtering out high-frequency noise without compromising signal integrity for general analog use.
The EL3061 terminal sustains a maximum dielectric strength of 30 V to insulate internal circuits from overvoltage situations that could occur in use or installation. Made with a polycarbonate enclosure, this terminal ensures high durability, easy installation, and handling while maintaining a weight of around 60 grams. This terminal’s miniature size of 12 mm (width) x 100 mm (height) x 68 mm (depth) supports high-density I/O configurations to allow compact utilization of cabinet space in intricate control systems. This input terminal is vibration resistant according to the EN 60068-2-6 standard to help in working stably at locations that experience continuous mechanical vibrations.
Frequently Asked Questions about EL3061:
Q: Why does the EL3061 use 16-bit signed presentation for 12-bit input?
A: It provides compatibility with control systems requiring signed values and reserves bits for scaling. This helps improve data handling without losing resolution.
Q: How does the 130 kΩ input resistance of EL3061 benefit signal integrity?
A: High resistance ensures minimal current draw from the signal source. It avoids loading effects and preserves original signal levels.
Q: What role does the 1 kHz filter play in analog signal processing?
A: It suppresses high-frequency noise while maintaining responsiveness. This is crucial for clean voltage readings in environments with electrical interference.
Q: Why is polycarbonate used for the EL3061 housing?
A: Polycarbonate offers high mechanical stability and electrical insulation. It also keeps the module lightweight for panel integration.
Q: Can the EL3061 withstand voltage surges during transient conditions?
A: Yes, it has a dielectric strength of 30 V. This provides protection against unexpected voltage spikes at the input.
