Technical Specifications Rated supply voltage is 24 V DC. Working temperature range is 0 ℃‑60 ℃. Equipped with multi‑mode fiber ports. Supports internal control system bus protocol. Meets industrial EMC anti‑interference standard.
Functional Features Implements optical‑electrical signal conversion. Supports bidirectional data transmission. Provides channel fault diagnosis function. Supports hot‑plugging under system allowable condition. Has power‑on self‑check mechanism.
Application Scenarios Used in petrochemical, power generation and heavy‑industry DCS cabinets. Applied for remote rack interconnection. Deployed in field with severe electromagnetic disturbance.
Performance Parameters Maximum communication distance depends on matched multi‑mode fiber. Built‑in fault LED prompt. Low power consumption design. Supports real‑time control data transmission.
Material Composition Circuit board uses high‑temperature resistant epoxy glass‑fiber material. Housing uses flame‑retardant plastic. Optical transceiver components are industrial grade. Contact pins adopt gold‑plated anti‑corrosion treatment.
Structural Characteristics Plug‑in rack‑mount structure. Front panel contains fiber sockets and status LED indicators. Rear side connects to system backplane. Size matches standard DCS module slot.
Working Principle Optical signal is received by transceiver and converted into electrical signal, then transmitted to system backplane bus. Outgoing electrical signal is converted into optical signal and sent out through fiber port. Built‑in circuit monitors link state continuously.
Installation Requirements Insert module into designated rack slot reliably. Guarantee cabinet grounding compliance. Fiber cable bending radius shall satisfy manufacturer requirement. Maintain good cabinet ventilation.
Usage Notes Prohibit direct contact of optical port core. Prevent dust contamination on fiber end face. Do not subject module to violent collision. Complete power‑off operation before removing module. Regularly inspect communication link status.
