Information About EL3314
The EL3314 is part of Beckhoff’s EtherCAT Terminal system and is engineered for accurate temperature measurement in industrial automation environments. An onboard microprocessor handles linearization across the entire temperature range and supports multiple thermocouple types, allowing flexible configuration per channel. Internal temperature sensing enables cold junction compensation, while optional external compensation can be configured when required. The terminal also supports precise millivolt measurements, expanding its applicability beyond thermocouple sensing to general low-voltage signal acquisition tasks.
Key Features
- Four Independent Thermocouple Channels: Supports simultaneous measurement of up to four thermocouple sensors with individual configuration per channel.
- Wide Thermocouple Compatibility: Handles common industrial thermocouple types including B, E, J, K, N, R, S, and T.
- Integrated Linearization and Compensation: Onboard microprocessor performs full-range linearization and cold junction compensation for accurate readings.
- mV Measurement Capability: Enables direct measurement of low-voltage signals in addition to temperature sensing.
- Wire Break Detection: Channel-specific diagnostics with LED indication improve reliability and fault detection.
- High Resolution and Accuracy: 16-bit resolution with adjustable scaling ensures precise temperature and voltage measurement.
- EtherCAT Integration: Seamlessly integrates into Beckhoff EtherCAT systems with galvanic isolation for signal integrity.
The EL3314 delivers the reliability and precision required for accurate temperature and low-voltage signal acquisition in Beckhoff EtherCAT-based industrial automation systems.
