Product Overview

The TB842 is a high-performance ModuleBus Optical Port Cluster Modem manufactured by ABB. Designed for robust industrial control applications, this module enables high-speed, noise-immune fiber optic expansion for ModuleBus communication networks. Operating at a 650 nm wavelength with data transmission speeds up to 10 Mbit/s, the compact unit weighs approximately 90g (0.20 lbs) and features full line and module redundancy support, hot-swap capability, and Agilent Versatile Link connectors for reliable field operation.

Core Technical Advantages

  • Redundant Optical Links: Supports both module and line redundancy to ensure uninterrupted system communication during network faults.
  • Noise-Immune Transmission: Utilizes 650 nm fiber optic technology for high-speed (10 Mbit/s) data transfer isolated from electromagnetic interference.
  • Hot-Swappable Design: Allows quick online replacement without powering down the system, reducing maintenance downtime.
  • Marine & Hazardous Location Certified: Holds ATEX Zone 2, cULus Class 1 Zone 2, and major marine agency approvals (ABS, BV, DNV-GL, LR).
