EJ1957-0000 by Beckhoff

The EJ1957-0000 from Beckhoff in the EJ EtherCAT Plugins series is a specialized safety module engineered for industrial automation. It is designed to integrate TwinSAFE Logic and supports 8-channel digital inputs, ensuring robust detection of safety-critical signals. Built to operate with a 24 V DC supply, this module can serve as a standalone safety controller or as an I/O device, meeting the rigorous demands of modern process control and safety systems.

Detailed technical specifications include a typical current consumption from the E-bus of 330 mA, and a rapid response time of approximately 4 ms for input reading and output writing. The module features 4-channel digital outputs which, in conjunction with its configurable test pulse settings, allow for precise system calibration and fault detection within a parameterizable watchdog framework. Its inherent design leverages the TwinSAFE/Safety over EtherCAT protocol, providing seamless communication for safety applications.

Further benefits include an output current capability of 0.5 A and a compact, lightweight construction weighing only approx. 64 g. The module is environmentally robust with an IP20 protection rating, making it ideal for indoor industrial use. Additional standards compliance with EN ISO 13849-1:2015 (Cat. 4, PL e) and EN 61508:2010 (SIL 3) ensures that the product meets modern safety benchmarks. Together, these features deliver a reliable, efficient solution for automated industrial systems requiring precise safety monitoring and rapid fault response capabilities.
