Description
Secure Long-Distance Signal Isolation
The HL-2CC Contact Closure Fiber Converter is a professional-grade fiber optic extender engineered to transmit two channels of forward, unidirectional contact closure signals over a single fiber link. Utilizing a high-performance photoelectric isolation scheme, the system ensures total electrical separation. This advanced safety configuration guarantees the secure transmission of switch signals, control pulses, and alarm triggers across long distances while protecting sensitive terminal equipment from destructive electrical surges and ground loops.
Flexible Interface and Media Configuration
Designed to accommodate diverse industrial needs, the HL-2CC Contact Closure Fiber Converter handles voltage-free dry contact signals with a default state of normally open mode, though normally closed operation can be made available upon request. For expanded system capabilities, the device offers an optional configuration to support 100M Ethernet data transmission alongside standard terminal connections. The core optical infrastructure supports both single-mode and multi-mode fiber compatibilities, providing a standard transmission reach of 500 meters over multi-mode or 20 KM over single-mode fiber that can be structurally customized up to 120 KM.
Industrial Durability and Zero-Configuration Deployment
The HL-2CC Contact Closure Fiber Converter features a true plug-and-play design that operates entirely without software settings, network IP addressing, or manual tuning. Built to withstand intense electromagnetic interference, it delivers rugged structural stability to ensure consistent and accurate signal triggering in harsh industrial environments. The system must be deployed as a pre-configured matched pair split between a dedicated transmitter (TX) and receiver (RX), making it an ideal choice for remote gate control, PLC signal extension, and automated alarm monitoring.
