Rockwell Allen‑Bradley 1786-RPFRXL/B Product Description
Rockwell Allen‑Bradley 1786-RPFRXL/B is an extra-long fiber ring repeater module for ControlNet industrial communication networks. This fiber ring repeater module regenerates optical signals and builds redundant ring topology to meet long-distance network transmission requirements. The compact fiber ring repeater module adopts DIN rail mounting for installation inside control cabinets. This fiber ring repeater module extends communication distance and protects nearby PLC and remote I/O modules.

1786-RPFRXL/B delivers reliable optical signal regeneration to retransmit ControlNet data over long-distance fiber links. Efficient optical signal regeneration limits signal attenuation generated during long-distance data transmission. Stable optical signal regeneration prevents abnormal network disconnection of sensors and automation actuators. Dependable optical signal regeneration ensures stable operation of the whole automation control system.

This unit features dual fiber channel circuit with rigid metal housing for electromagnetic shielding. The robust dual fiber channel circuit blocks external electromagnetic interference from entering the optical communication circuit. The sealed dual fiber channel circuit reduces optical signal loss and improves network transmission performance. This durable dual fiber channel circuit stays stable under cabinet vibration and temperature variation.

Rockwell Allen‑Bradley 1786-RPFRXL/B is widely matched with ControlNet adapters and ControlLogix PLCs in chemical, power and large manufacturing control systems. It is equipped with fiber optical connectors for simple and secure wiring connection. It is original spare part for retrofit and maintenance of Rockwell legacy ControlNet fiber communication systems.
