Product Description:
The Beckhoff range of plug-in modules in the EtherCAT series includes the EJ1889-1005 is a high-performance module that provides 16 digital input channels. It is designed to efficiently capture binary control signals in industrial automation systems. The module utilizes ground-switching technology to manage and interpret control signals. A "0" signal voltage is defined between 18 to 30 V, while a "1" signal voltage is within the range of 0 to 7 V. This distinction allows the module to differentiate between active and inactive states, ensuring precise input detection. The wide range for the "0" signal voltage helps to maintain stable signal recognition for system reliability.
Each channel on the EJ1889-1005 module has a rated 3 mA input current. The module handles noise and signal fluctuations efficiently owing to its integrated 3 ms input filter. This ensures that the module operates with high precision in demanding applications where accuracy is critical. The module’s rated E-bus current consumption is 80 mA. This level of consumption ensures optimal performance without placing high energy demands on the system. For enhanced safety, the unit boasts an electrical isolation of 500 V that protects the module and devices connected in case of voltage fluctuations.
The EJ1889-1005 meets rigorous safety and performance standards, featuring both CE and UL approvals. Its robust build also ensures that it is protected from ingress by solid objects per IP 20 guidelines. The module is also adaptable to challenging conditions since it has been built to resist shock and vibrations, ensuring reliable performance in harsh environments. This unit should not be exposed to condensation. It is suited for -25 to +60°C and should be mounted on a signal distribution board.
