Product Description:

The EL2262 is a high-performance EL EtherCAT Terminal which is designed for precise and fast digital output operations. This input terminal has a 4-wire connection type and provides stable, reliable, and secure connections for high-demand industrial applications. The current limitation of this terminal is typically rated at 4 A over 150 μs to protect both the terminal and all downstream devices from abnormally high current surges.

This terminal features 2 independent output channels, each of which provides a maximum output current of 0.5 A in push operation. Each channel is short-circuit proof and provides system protection in case of overloads while maintaining stable operational consistency. The configuration of the EL2262 input terminal is managed using the TwinCAT system, which allows simple setup, parameter adjustment, and full integration. This terminal supports distributed clocks with an accuracy of much less than 1 µs, which is important to achieve exact synchronization across large EtherCAT systems. This input terminal features an output rate of up to 1 Msample/s with a minimum cycle time of 1 µs to support the high-frequency signal output demands in applications where timing is critical.

With regards to mechanical reliability, the shock resistance of this EL2262 input terminal is followed by the EN 60068-2-27 standard to operate comfortably even in abusive or high-vibration industrial conditions. To safeguard connected systems, this terminal includes reverse voltage protection to prevent wrong connections and incorrect wiring. The breaking energy per channel is set at less than 150 mJ to avoid damage to this terminal’s internal components from switching effects or load removal. In this input terminal, the average current consumption at the power contacts is 35 mA plus the output load, to guarantee more efficient energy utilization even during continuous high-speed operations.

Frequently Asked Questions about EL2262:

Q: How does the oversampling factor improve signal accuracy in the EL2262?

A: The adjustable oversampling factor (1–1000) enables finer time resolution for output signals. This leads to more accurate and dynamic control in high-speed applications.

Q: Why is reverse voltage protection critical in the EL2262 EL EtherCAT Terminal?

A: Reverse voltage protection prevents damage during wiring errors or polarity mistakes. It safeguards internal circuits and maintains long-term reliability.

Q: What role does short-circuit proofing play in the EL2262 outputs?

A: Short-circuit protection ensures that if an overload occurs, the terminal isolates the fault. This keeps the system operational without damaging the output channels.

Q: How does the EL2262 handle current surges during fast switching?

A: The EL2262 uses a typical current limitation of 4 A over 150 μs. This feature protects both terminal and connected devices from harmful peak currents.

Q: Why is the breaking energy specification important for the EL2262?

A: With <150 mJ/channel, the breaking energy minimizes mechanical and thermal stress. This extends the operational life of both the terminal and connected loads.
