Product Description:

The EJ7047-0000 features a EJ-24-2x16pin housing which is specifically designed for use as an EtherCAT I/O plug-in module. It is a Beckhoff unit that features a single channel designed for controlling stepper motors. It also comes equipped with two inputs that function in end position detection, allowing for precise limit switch functionality. It has one input that is dedicated to encoder feedback, which helps to facilitate accurate closed-loop control. For outputs, the module provides a connection for a two-phase stepper motor, enabling efficient motor operation, and one configurable output for a motor brake, capable of handling up to 0.5 A.

This EtherCAT plug-in module is designed to operate with a 2-phase stepper motor, accommodating both unipolar and bipolar configurations. This allows users to select the appropriate motor type based on their application requirements. The unit is rated for 48 VDC, operating effectively on 8 to 48 V DC. This allows the module to be integrated into various systems without the need for specialized power sources. The connection is facilitated through a distribution board, ensuring a reliable and stable power delivery to the module and connected peripherals.

The module features an encoder input signal that operates within a range of 5 to 24 V DC, typically drawing around 5 mA. This single-ended encoder input is designed to facilitate effective communication between the module and the connected encoder, allowing for accurate position feedback and enhanced motion control. It supports a maximum input frequency of 400,000 increments per second, allowing for rapid and precise monitoring of encoder signals. The module has low energy demands and boasts a 140 mA consumption on the E-bus.
