Secure isolation: lightcoupled isolation minimizes interference between connected devices, ensuring safe operation of the equipment and protecting sensitive electronics. Dependable operation: engineered to maintain stable performance in critical systems, reducing the risk of failures and downtime. Visual status feedback: builtin LED indicator provides clear, realtime status updates to simplify monitoring and diagnostics during operation. Flexible control: supports both level and lowlevel trigger inputs, enabling compatibility with a broad range of control architectures and configurations. Use scenarios Industrial automation and process control: isolates noisy sensor or actuator lines from the controller to prevent interference, protecting the control system and ensuring reliable operation in harsh environments. Laboratory instrumentation and data acquisition: provides safe separation between test gear and the data logger or controller, preserving measurement integrity and equipment safety. Building automation and smart systems: interfaces with PLCs or microcontrollers using different trigger levels, enabling flexible integration across diverse control networks.
