BECKHOFF ELX3152-0090 EtherCAT Terminal

Description

Directing high-precision analog measurements in hazardous environments, the ELX3152-0090 is an intrinsically safe analog input terminal designed for the direct integration of field devices from Zone 0/20 explosion-hazard areas. This 2-channel single-ended interface processes standard 0/4 to 20 mA current signals with 16-bit resolution. Integrated with TwinSAFE SC (Single Channel) technology, the terminal enables safety-supporting signals to be analyzed and utilized within standard industrial control systems, expanding diagnostic depth and process safety across complex control architectures.

Features

• Direct connection of intrinsically safe field devices from Zone 0/20 and Zone 1/21.
• Two independent single-ended analog input channels supporting 0 to 20 mA and 4 to 20 mA signals.
• TwinSAFE SC capability for integrating safety-assisting monitoring functions.
• High-resolution 16-bit representation for highly accurate field instrument monitoring.
• Supports Distributed Clocks (DC) for highly synchronized and precise EtherCAT process data acquisition.
• Advanced internal processing options including activatable digital FIR/IIR filters.
• Diagnostic compliance with NE43 NAMUR sensor limit specifications.

Applications

• Oil and gas extraction, processing, and refining facilities.
• Chemical and petrochemical process plants requiring intrinsic safety (Ex i).
• Industrial wastewater treatment facilities with explosive gas atmospheres.
• Pharmaceutical processing lines managing volatile substances.
