Product Description:
The EL3122 is basically integrated into EL EtherCAT Terminals series as a high-precision analog input terminal suitable for flexible signal acquisition. This Beckhoff’s module provides for two channels doubling data acquisition per module. It is an analog input terminal that reads real-world voltages. It takes a voltage, single-ended input type and allows for easy wiring and sensor compatibility. The device reads ±10 V input voltage range for accommodating standard industrial sensors.
It digitizes signals to 16-bit resolution which ensures high measurement granularity. Additionally, it presents 200 kΩ input impedance and thus minimizes sensor loading. It converts data in ≤ 1 ms conversion time to support fast control loops. The model features two signal LEDs per channel, enabling instant status checks. It connects via a two-wire connection type which eses field wiring. The terminal consumes power directly from the E-bus which limits the use of external supply lines. This EtherCAT EL3122 unit consumes approx. 100 mA from the E-bus and also reduces panel power requirements.
It runs between 0 °C and 55 °C temperature values, suitable for a common factory climate. The hardware measure 15×100×68 mm to save rack space in dense installations. This module carries IP20 protection rating so to shields against solid intrusion. It also uses differential inputs with a common internal ground which suppresses interference for clean readings. By limiting input currents above 40 mA via internal overcurrent protection, it guards the system against damage. The part offers 500 V isolation between the E-bus and signal circuits, signifying safe separation of power and data. This filters inputs at 5 kHz which reduces high-frequency noise and enhances signal clarity.
Frequently Asked Questions about EL3122:
Q: How much does EL3122 load the signal source?
A: EL3122 presents 200 kΩ input impedance which minimizes influence on the sensor circuit. It maintains signal integrity under varying source impedances.
Q: How quickly does EL3122 convert signals?
A: This terminal completes conversions in ≤ 1 ms which supports rapid control feedback. This enhances loop performance in high-speed applications.
Q: What wiring does EL3122 require for connections?
A: It uses a two-wire connection type which streamlines analog line deployment further reduces terminal count and wiring complexity.
Q: Which protection class covers the EL3122 EtherCAT terminal?
A: The component carries IP20 which blocks solid particles larger than 1.0 mm. It prevents accidental finger contact with live circuitry.
Q: What power does EL3122 consume from the bus?
A: The EL3122 draws approx. 100 mA from the E-bus which lowers overall panel current needs. It reduces thermal load in bus-powered installations.
