The SD-I-U-EC from K.A. Schmersal GmbH & Co. KG is an EtherCAT gateway designed for integrating safety sensors and protective devices into industrial networks. It enables serial diagnostics of safety components via the EtherCAT communication protocol, efficiently transmitting comprehensive diagnostic data to the higher-level control system.

The device features an integrated status display with one LED, indicating the operating status. It is mounted using a quick-mount system for DIN EN 60715 rails, allowing for fast and easy installation. The connection is made via spring-loaded terminals, ensuring a secure and vibration-resistant connection.

The SD-I-U-EC provides high electromagnetic compatibility according to EN 61000-4-2, EN 61000-4-4, and EN 61000-4-5, making it reliable even in environments with high electromagnetic interference. The housing has a protection rating of IP20, making it suitable for use in control cabinets. The device operates at 24 VDC and has a rated operating current of 500 mA.

With compact dimensions of 50 mm width, 100 mm height, and 80 mm depth, the device can be installed in space-constrained areas. It is ideal for applications requiring the integration of safety sensors into industrial networks using EtherCAT.
