Product Description:

The EL1852 by Beckhoff is an 16-channel digital I/O terminal for EtherCAT systems. It is designed to handle both input and output tasks, making it versatile for a variety of industrial automation applications. The terminal features 8 inputs and 8 outputs for data communication within EtherCAT systems. The terminal can simultaneously receive data from sensors while sending control signals to actuators, ensuring seamless two-way communication. The terminal utilizes flat-ribbon cable connection technology for easy and compact wiring. The flat-ribbon cable ensures secure and efficient transmission of data between devices, while also making it easier to manage and organize cables within tight spaces. This supports faster installation and maintenance, improving the overall efficiency of the system setup.

The EL1852 can safely handle up to 1 amp of current for each individual connection. It is designed to support different load types including ohmic, inductive and lamp loads. This flexibility allows the terminal to integrate seamlessly with various setups and system requirements. This unit offers a maximum output current of 0.5 A per channel, ensuring the system operates within safe electrical parameters. It also comes with additional safeguards including reverse voltage protection, preventing costly repairs or replacements.

This terminal has a typical current consumption of 100 mA on the E-bus, which is modest enough to ensure that the terminal does not place a significant load on the overall system. The E-bus and field potential are electrically isolated up to 500 V to protect sensitive components from voltage spikes. For optimal performance, this terminal should be operated in ambient temperatures in the 0 to 55°C. It features ingress protection against larger particles but users should note that the terminal is not moisture or dust-proof.
