The EL3121 analog input terminal handles signals in the 4 to 20ma range. The current is digitized to a 16-bit resolution and transmitted to a higher level of automation through electrical isolation. The input channel of the EtherCAT terminal has a differential input and a common internal ground potential. The EL3121 is a single-channel version that features fine granularity and electrical isolation. Lead break or overload detected. The terminal state is passed to the controller via the e bus. The EtherCAT terminal displays its signal status via a light-emitting diode. The error led indicates overload conditions and disconnection.

An Analog Input Terminal is an input port or interface used to receive and process analog signals. Analog signals are electrical signals that change continuously, such as voltage, current, temperature, pressure, etc.

Analog input terminals are typically used to connect sensors, measuring instruments, or other analog devices to transmit the analog signals they generate to a computer, data acquisition system, or control device for processing and analysis.

EL3121 analog input terminals generally have the following characteristics:

1. Input range: EL3121 Analog input terminals can usually accept analog signals within a certain range, such as 0 to 10V, 4 to 20mA, etc. The input range depends on the design and application requirements of the terminal.

2. Resolution: The resolution of the EL3121 analog input terminal refers to the minimum analog signal change that it can resolve. The higher the resolution, the richer the details of the signal that the terminal can detect.

3. Sampling rate: Sampling rate refers to the number of times per second that the analog input terminal samples the analog signal. The higher the sampling rate, the faster the signal that the terminal can capture changes.

4. Anti-interference ability: The analog input terminal usually has a certain anti-interference ability to reduce the impact of external interference on the analog signal.

5. Interface type: EL3121 Analog input terminals can be connected to external devices through different interface types, such as BNC, RCA, and Phoenix terminals.

Analog input terminals are widely used in industrial control, instrumentation, scientific research, medical equipment and other fields, which are used to collect and process various analog signals to realize the monitoring and control of physical quantities.
