Product Description

Description

The EL1262-0050 is a specialized EtherCAT Terminal from Beckhoff designed for high-speed signal acquisition. Featuring 2 channels with a nominal voltage of 5 V DC, this terminal excels in applications requiring precise timing, such as high-resolution event logging. Its key advantage is its oversampling capability, allowing it to sample input signals at up to 1 Msample/s (n = 1...1000 factor), providing an extremely fine-grained view of signal states that exceeds standard cycle times.

Features

Oversampling Capability: Enables signal sampling at rates higher than the bus cycle time (max. 1 Msample/s).
High-Precision Timing: Features Distributed Clocks (DC) support with precision << 1 µs, making it ideal for synchronized timestamping.
Compact Design: Integrates advanced processing into a standard 12 mm wide housing.
Flexible Input Logic: Supports 5 V DC logic signals, common in TTL-based sensors or high-speed encoder feedback interfaces.
Galvanic Isolation: Ensures 500 V isolation between the E-bus and field potential, protecting the controller from signal-side surges.

Installation and Integration Notes

Wiring: Utilizes 4-wire connection technology. Connections support solid (0.08–2.5 mm²) and flexible (0.14–1.5 mm²) conductors.
Sync Configuration: Because this terminal uses Distributed Clocks, ensure that the EtherCAT Master (e.g., TwinCAT) is configured to synchronize the terminal's internal clock to the master clock to achieve the specified < 1 µs precision.
Process Image: The process image includes both the input data and a 64-bit CycleCounter/latch, which is essential for tracking when specific samples occurred relative to the bus cycle.
Environment: Designed for operation between 0 °C and +55 °C. Ensure proper airflow in the control cabinet when using multiple high-density terminals.

FAQ

What is the primary advantage of the oversampling feature on this terminal?

Oversampling allows the terminal to sample input signals at a rate higher than the EtherCAT bus cycle, capturing transient signal states that would otherwise be missed.

Does the EL1262-0050 support Distributed Clocks?

Yes, it supports Distributed Clocks with a precision of << 1 µs, allowing for accurate timestamping of events.

What signal voltage level is required for this terminal?

The terminal is designed for a nominal voltage of 5 V DC.

How is the oversampling factor defined?

The oversampling factor (n) is an integer multiple of the cycle time, configurable between 1 and 1000.
