Product Description:

The Beckhoff's manufactured EK1960-0000 is an EtherCAT Coupler used in industrial automation systems where high-speed signal processing and space-efficient integration are needed. This coupler offers high-speed control through a minimum cycle time of about 1 millisecond, required in precise and critical operations.

This coupler integrates a high number of 20 digital inputs and 24 digital outputs, with an optional 4 relay outputs for further control capabilities. These I/O capabilities make this coupler suitable for applications that require a high density of signal connections within minimal space. This coupler allows efficient wiring between outputs and actuators with a 30-meter cable length, provided that 0.75 mm² cross-sectional area cables are used. The EK1960-0000 coupler comes with a watchdog timer that can be configured from 2 milliseconds to 60000 milliseconds, which allows adaptable safety and monitoring capabilities based on particular system needs. The EK1960-0000 EtherCAT coupler has a 24 VDC voltage supply and SELV/PELV-approved safety, thus providing a range of safe operating voltage from –15% to +20%. The internal 5V and up-to-500-mA E-bus power supplies of this coupler guarantee a stable power supply and communication reliability across connected EtherCAT terminals.

Physically, this EK1960-0000 coupler is compact and weighs approximately 500 grams, so that it can be accommodated in control cabinets with limited space. This coupler also possesses a protection rating of IP 20, according to IEC 60529, and can be used in environments with a pollution degree level of 2. This coupler’s input image is dynamic and is configured by TwinSAFE in TwinCAT 3 to allow precise mapping of safety functions. The working ambient temperature range of this coupler is from -25 °C to +55 °C, where it remains stable in operation with changing climate conditions.

Frequently Asked Questions about EK1960-0000:

Q: How does the dynamic input process image benefit system configuration?

A: It allows real-time I/O allocation adjustments through TwinCAT 3. This enables efficient resource usage and flexible safety mappings.

Q: Why is a 500 mA E-bus power limit important for the EK1960-0000?

A: It ensures reliable power supply to connected EtherCAT terminals. This prevents voltage drops and supports stable communication.

Q: How does the 30 m cable length support field installation?

A: It allows installation of actuators far from the control cabinet. This flexibility reduces wiring complexity in distributed systems.

Q: What role does the watchdog timer play in EK1960-0000 operation?

A: It monitors system response times and triggers safety actions if delays occur. This enhances protection against communication failures.

Q: Why is SELV/PELV compliance important for this device?

A: It ensures user safety by limiting touch voltage levels. This compliance also aligns with electrical safety standards in automation.
