Dry Contact Closure over Fiber

Transwan Contact Closure to Fiber device is a specialized converter that transmits contact closure signals over fiber optic cables. it allows relay-based or dry-contact signals to be securely and reliably extended over long distances using fiber optics, ensuring immunity to electromagnetic interference (EMl), radio frequency interference (RFl), and ground loops. These devices are commonly used in industrial automation, security systems, remote monitoring, and access control applications. They support multiple contact channels and can work over single-mode or multi-mode fiber depending on the application requirements.
