Beckhoff EL3048 EtherCAT Terminal Analog Input, 0–20 mA, 12-bit, 12×100×68 mm

Overview

The Beckhoff EL3048 is an 8-channel analog input EtherCAT Terminal for 0–20 mA current signals. Each channel is digitized at 12-bit resolution and transferred electrically isolated to the controller. Inputs are single-ended with the 0 V power contact as the common reference. The compact 12 mm housing provides high channel density with per‑channel LED indication.

Key Features

• Eight single-ended current inputs (0…20 mA)
• 12-bit resolution (16-bit presentation incl. sign)
• Default conversion time 1.25 ms (configurable, multiplexed)
• Input filter limit frequency: 1 kHz
• Electrical isolation between E-bus and signal voltage: 500 V
• Activatable FIR/IIR filters and limit value monitoring

Applications

• Acquisition of 0–20 mA process signals from transmitters and sensors
• Space-constrained EtherCAT panels needing high-channel-density analog inputs
