Product Description

Overview

CU1123 | Infrastructure, 3-port connection point, EtherCAT, 100 Mbit/s, 24 V DC, RJ45 linear, tree or star topology.

The CU1123 is primarily used for cascading EtherCAT networks, providing a compact solution for EtherCAT networks. EtherCAT can practically handle almost any topology.

The 3-port CU1123 EtherCAT connector represents a compact cascading approach for EtherCAT networks. Constructed externally to the EtherCAT terminal system, this DIN rail-mounted EtherCAT connector serves as an alternative to the EK1122 EtherCAT coupler and the 8-port CU1128 EtherCAT connector.

Port Configuration & Technology

Port Configuration: Features three RJ45 ports (Port 1: Input; Ports 2 & 3: Additional couplers/modules).
Link Indicators: RJ45 ports with integrated link and activity status indicators.
Technical Specs: 100Mbit/s data transfer rate, 24V DC (-15% / +20%) power supply via 3-pin connection.
Hot Plugging: Permits link connection/disconnection during operation (with TwinCAT/EtherCAT Master).

*Note: This device cannot be used as a standard Ethernet switch.
