Product Description

The EK1818 EtherCAT coupler from Beckhoff Automation GmBH is a part of its EK1800 series of devices of the same type. This product is integrated with four digital outputs and eight digital inputs. The unit features a data transfer rate of 100Mbaud. It has several LEDs for diagnosing the power supply, the EtherCAT state machine/PLC, the Fieldbus as well as the digital inputs and outputs. The coupler must be used only with the manufacturer’s UL Listed EtherCAT system. It does not incorporate any firmware. The device has a typical short circuit current rating of less than 2A. The EtherCAT coupler comes with a one-year warranty.

This unit helps in communication between the high-level EtherCAT network and the terminals. In other words, it helps to connect the added terminals to its right side while on the left side it supports connection to a high-level network. This coupler has an IP 20 protection rating. It cannot be used with a switch or a router. The E-bus has an electrical isolation voltage rating of 500V. This product supports ferrule, stranded wire and solid wire type conductors. The device also encompasses reverse polarity protection. The EtherCAT unit has a power supply rating of 24VDC.

The coupler can be installed in any position. The ideal operating temperature range is between -25°C and 60°C. The unit has a typical time delay of 1µs. The product can be fitted on a mounting rail using mild pressure. It may be subject to electrostatic discharge in case of improper handling. The device has a maximum output current rating of 0.49A for each channel. The ferrule type conductor has a rated cross-section of 0.14 to 0.75 sq.mm. The EtherCAT coupler has a vibration resistance that conforms to EN60068-2-6 specifications. This product can be delivered to any address worldwide through our trusted global delivery partners.
