Product Description:

The market giant Beckhoff has supplied EL6752-0010, which is a member of the EL EtherCAT Terminals type for trouble-free fieldbus integration. It is a PROFIBUS Coupler that bridges the PROFIBUS networks to the EtherCAT I/O nodes. This innovative module exposes two PROFIBUS bus interfaces allowing network configuration in the form of daisy chain topology. It mainly utilizes twisted pair transmission mediums that improves signal integrity over long distances.

This terminal interface transfers data at up to 12 Mbaud with automatic baud-rate detection which adapts instantly to network speed changes. This isolates PROFIBUS and E-bus at 500 V, preventing ground-loop interference. The variant consumes power directly from the E-bus and eliminates extra power wiring. It consumes typically 250 mA on the E-bus which keeps overall module current demands low. It works between 0 °C and 55 °C and this range maintains reliable operation at varied industrial settings. The gadget occupies just 15 mm × 100 mm × 68 mm space which conserves valuable DIN-rail space. It snaps onto DIN rails which accelerates installation and replacement.

EL6752-0010 terminal weighs approximately 70 g to minimize the top-rail load. It can tolerate up to 95% relative humidity without condensation which suits humid production environments. This feature supports up to 125 PROFIBUS slaves which scales large device networks. The product achieves PROFIBUS cycle times down to 200 µs, enabling high-speed I/O synchronization. It also withstands electrostatic discharges up to 4 kV contact for preserving module integrity under ESD events. It further balances compact dimensions and robust electrical performance for efficient PROFIBUS-to-EtherCAT coupling.

Frequently Asked Questions about EL6752-0010:

Q: How many devices can the EL6752-0010 support on PROFIBUS?

A: It supports up to 125 PROFIBUS slaves which scales extensive I/O networks and accommodates large automation systems without additional couplers.

Q: What is the significance of EL6752-0010’s E-bus power draw?

A: The EL6752-0010 draws typically 250 mA from the E-bus which minimizes overall system current. It reduces the need for external power supplies in compact setups.

Q: How does EL6752-0010’s form factor benefit panel design?

A: This terminal type measures 15 mm wide which conserves DIN-rail space, thus allows higher I/O density in control cabinets.

Q: What temperature range suits the EL6752-0010?

A: The EL6752-0010 operates from 0 °C to 55 °C which matches standard industrial environments. It prevents performance issues in both cool and heated areas.

Q: How does EL6752-0010 maintain signal quality over long distances?

A: The variant uses twisted-pair cabling which preserves signal integrity. As a result, it reduces data errors on extended PROFIBUS lines.


Internal Product Review

  • ‘‘The EL6752-0010 EtherCAT terminal provides 500 V isolation and keeps PROFIBUS and EtherCAT grounds separate which prevents communication faults. Its 95% humidity tolerance avoids condensation failures in moist environments. This Profibus coupler’s 15 mm width allows dense DIN-rail layouts without sacrificing connectivity.’’
