Product Description:
The Beckhoff EL3142 EtherCAT Terminal serves industrial automation procedures across different application ranges.
The terminal includes 2 single-ended inputs for receiving analog signals between 0 and 20 mA that measure current signals effectively. The EL3142 receives its power through the E-bus connection to maximize energy efficiency on the system level. The high-precision data acquisition performance comes from the 16-bit resolution, which includes sign processing in the terminal. The device incorporates 85 Ω of internal resistance in addition to diode voltage to provide dependable signal conditioning for its operation. The input filter of this terminal functions at 5 kHz limits, which grants adaptation to eliminate interference and increase signal refinement. The signal conversion duration stands at 60 µs, while the device has another mode that shortens the conversion time to approximately 40 µs. The device supports distributed clock synchronization at a precision level of 1 µs to maintain high accuracy throughout the entire system.
Reliable, high-quality measurement results are possible because the system delivers measurement errors below ±0.3% relative to its full-scale value. The terminal includes an FIR/IIR filter system that activates through software to boost signal processing and give users diverse filtering choices. The system includes limit value monitoring features that enable it to detect predefined threshold violations. The terminal's dielectric strength reaches 30 V to deliver safe operation in routine industrial operations. The E-bus requires 170 mA for the power supply to operate efficiently at the terminal.
