Product Description
ELM3004-0000 is a Beckhoff measurement terminal in the ELM EtherCAT Terminals series. It provides four differential analog input channels using a 2-wire connection. All four channels are converted simultaneously, preventing timing offsets between channel measurements, while the 10 ksps per-channel sampling rate supports time-aligned signal acquisition. The terminal offers 11 measuring ranges and 24-bit resolution for capturing small signal changes across different input levels. There is no isolation between the individual channels.
The analog-to-digital converter operates at 8 Msps and has a 2.6 kHz filter cutoff. The input filter has a 30 kHz cutoff to limit higher-frequency signal content before measurement, and its ramp-up time is 300 µs. The E-bus draws a typical current of 470 mA and has 707 V DC isolation. SGND isolation is also rated at 707 V DC. Typical thermal dissipation is 3 W. The IP20 protection class provides protection against contact with objects larger than 12.5 mm but does not protect against water.
