Product Description:

The Beckhoff ES5002 EtherCAT Terminal provides dual connection capabilities through its two operating channels for encoder installations.

The terminal allows dual encoder connections through a differential signal interface (D+, D-, Cl+, Cl-) that validates various types of encoder operation. The terminal accepts external encoder operating voltage through the EL91xx series, allowing users to select their preferred power supply. The ES5002 includes support for distributed clocks, which allows it to achieve precise time alignment with all EtherCAT devices present in the network. RS422 difference signals link both input and output signals to deliver reliable data transmission over extensive distances the way high-accuracy systems require. Industrial power systems supply power to the terminal through their 24 V DC power contacts for standard operation. The terminal supports adjustable data transfer speeds ranging from 250 kHz up to 1 MHz for processing-intensive applications. This terminal supports serial input configurations up to 32 bits while operating with 24 bits as default to process diverse encoder data types. Users can make the terminal suitable for their application through flexible baud rate and programming options, and data length features.

The device has an activatable power fail bit function that checks power disturbances and enables continued operation when power failures occur. With its weight of 55 g, the terminal functions as a small and convenient device to use in control systems. The operable temperature range for this device extends from -25°C to +60°C for industrial applications, yet its storage requirements span from -40°C to +85°C. Data transfer precision with the ES5002 is achieved by its use of the SSI (Synchronous Serial Interface) protocol. The device requires 45 mA of power consumption, which leads to its energy-efficient operation while not connected to an encoder.
