Product Description:

The EL3751 is a high-accuracy analog signal terminal that can handle voltage and current input modes, hence it is versatile to use for signal monitoring. The unit can have a sampling rate of 10,000 samples per second, which is sufficient to capture dynamic changes in inputs with high accuracy. It handles each signal with negligible delay of about one sample, hence it has a latency of about 100 microseconds.

This is low delay suitable for real-time feedback operations and time-critical functions. Terminal input impedance is also specified to be 100 kΩ on voltage inputs to avoid loading of referenced circuitry and protect signal integrity. For current input, the impedance is less than 250 ohms to provide meaningful measurement that is not interfered with. This capability in each mode of operation also makes EL3751 appropriate in multisensor systems with various types or systems requiring multi-function data capture. It is optimized for high-speed, accurate readings, and thus the unit can be used in applications that involve transient detection or waveform capture. The EL3751 terminal does not have a problem combining field-level analog signals to control-level digital systems. Its low signal delay along with high sampling rate offers dynamic and stable performance. In application for process monitoring, equipment feedback, or control, the terminal ensures accurate representation of signals. It is optimum in application for tracing quickly changing values or high detail of waveform capture. Its real-time capability ensures compatibility with time-synchronized data-requiring systems.

The EL3751 terminal operates consistently in all uses, and it delivers strong performance in a broad spectrum of electrical environments. It extends system performance via voltage and current signal modes. With fast sampling, low latency, and impedance adaptive performance, it is ideal for demanding analog input applications where speed and accuracy are critical to success in the system.
