Functions & Features
Long‑distance Fiber Optic CommunicationBased on 1550 nm single‑mode fiber transmission technology, it features low signal attenuation and long transmission distance, meeting the requirements of remote data transmission across regions and workshops on industrial sites. Compared with traditional copper cable communication, its stability and anti‑interference capability are significantly improved.
Multi‑Protocol CompatibilitySupports mainstream industrial communication protocols including Modbus RTU, PROFIBUS DP, and CANopen. It can seamlessly connect with ABB control systems such as AC800F and Relion®, and is also compatible with third‑party automation equipment, reducing system integration complexity.
High‑Reliability DesignAdopts industrial‑grade components and protective technology with an IP65 ingress protection rating, enabling adaptation to harsh industrial environments such as dust, humidity, and electromagnetic interference. The low‑power design (< 2 W) reduces both energy consumption and heat generation, ensuring long‑term stable operation.
Modular and Convenient DeploymentSupports DIN rail mounting. Its compact size and light weight facilitate integration and wiring in control cabinets. The modular structure allows quick replacement and maintenance, minimizing downtime and meeting the requirements for efficient on‑site industrial operation and maintenance.

Frequently Asked Questions (FAQ)
Q: What is the transmission distance of 1MRK002311-AAr02?A: As a 1550 nm single-mode fiber communication module, its transmission distance depends on fiber quality and on-site environment. It can normally support dozens of kilometers, fully meeting long-distance communication requirements in industrial sites.
Q: Which ABB control systems is this module compatible with?A: It is mainly designed for ABB AC800F series and also compatible with Relion® series. It can connect to other third-party control systems supporting Modbus RTU, PROFIBUS DP and other protocols via standard communication protocols.
Q: What should be noted during installation?A: A 24V DC power supply is required, and installation must strictly follow DIN rail mounting specifications. Only 1550 nm single-mode fiber patch cords should be used for fiber connection, avoiding excessive bending. The installation environment must meet the temperature range of -20℃ to +60℃ and IP65 protection requirements.
Q: What is the warranty policy for this module?A: A 1-year warranty is provided for normal use of brand-new original products. Non-human-induced damage within the warranty period is eligible for repair or replacement.
Q: Does this module support hot-plugging?
A: Hot-plugging is not supported under normal conditions. Installation, removal or replacement must be performed after the system is powered off to prevent equipment damage and data transmission interruption.
