Product Description

Description

The BECKHOFF ELX3312-0090 is a high-precision, 2-channel analog input EtherCAT Terminal designed for direct temperature measurement using thermocouples located in explosion-hazardous areas. Featuring intrinsic safety (Ex i) interfaces, this terminal permits the direct connection of sensors installed in Zone 0/20 and Zone 1/21 hazardous environments, providing a highly integrated solution for process technology applications.

In addition to its intrinsically safe capabilities, the BECKHOFF ELX3312-0090 incorporates TwinSAFE SC (Single Channel) technology. This enables the use of standard analog signals for safety-directed tasks within a TwinSAFE system, allowing the transmission of process data to a TwinSAFE Logic terminal for safety-related evaluation and processing.

This compact 12 mm terminal supports a wide array of thermocouple types, performing high-resolution, low-noise analog-to-digital conversion. To maintain isolation and safety parameters, the terminal must be integrated into an EtherCAT segment powered by an ELX9560 power supply terminal.

Features

Intrinsically safe (Ex i) inputs for direct connection of field devices in hazardous locations
TwinSAFE SC (Single Channel) technology for safety-oriented process data evaluation
Two differential analog input channels dedicated to high-accuracy thermocouple measurement
Wide sensor compatibility supporting thermocouple types K, J, L, E, T, N, U, B, R, S, and C
High-resolution 16-bit analog-to-digital conversion
Integrated cold junction temperature compensation and characteristic curve linearization
Compact DIN rail mounting with diagnostics indicators via integrated LEDs

Applications

Intrinsically safe temperature monitoring in chemical, petrochemical, and gas processing plants
Thermocouple signal acquisition from Zone 0/20 and Zone 1/21 hazardous zones
Safety-related temperature monitoring systems using TwinSAFE SC architectures
Process engineering automation requiring compact, hazardous-area-compliant I/O solutions

Installation Guidelines

Ensure all power supplies are fully de-energized before mounting, wiring, or configuring the terminal.
Mount the terminal on a standard 35 mm DIN rail (EN 60715) with secure locking.
Verify that the terminal is positioned within an EtherCAT Terminal segment that is powered downstream of an approved ELX9560 power supply terminal to ensure intrinsically safe power distribution.
Observe all mandatory Ex i isolation distances, separation guidelines, and wiring classifications for hazardous-area installations.
Ensure correct thermocouple polarity during wiring to avoid measurement offset and errors. Ensure shield grounding is executed in accordance with local hazardous area regulations.
