Product Overview

The ABB NMBA-01 (3BHE035093R0001) is a compact fieldbus adapter module designed for seamless integration with ABB drive systems, including the ACS 300, ACS 400, ACS/ACP/ACF 600, and DCS 500. It establishes efficient, deterministic communication across multi-drive networks by bridging electrical Modbus lines and optical DDCS channels. This module guarantees high-speed data transmission and reliable process control while protecting your equipment from industrial electrical noise.

Core Technical Advantages

  • Dual Protocol Support: Handles high-speed Distributed Drive Communication System (DDCS) and standard Modbus protocols on a single footprint.
  • Flexible Multi-Drive Topology: Links 2 standalone sites natively, and scales from 3 up to 248 sites when running in multi-drive control mode.
  • Robust Optical Isolation: Utilizes specialized fiber optic connections to completely eliminate ground loops and electromagnetic interference between connected drives.

Technical Specifications

Parameter Specification Details

Installation & Engineering Guide

  • Optical Handling: Match color-coded HP universal connectors precisely (Blue to receiver, Gray to transmitter). Do not exceed a short-term bending radius of 25 mm or a long-term bending radius of 35 mm for the plastic fiber optic cables to avoid breaking the 1 mm core.
  • Cable Restrictions: Limit copper Modbus lines to 1,200 meters using Belden 9841. Restrict point-to-point plastic fiber runs to a maximum of 10 meters to prevent attenuation from exceeding the 0.31 dB/m threshold.
  • Mechanical Loads: Wire via the 8-pin MVSTBW terminal (maximum 2.5 mm² wire size). Keep long-term tensile strength below 50 N and long-term tensile load under 1 N during routing.

Technical FAQs

Q1: Which ABB drive systems are compatible with the NMBA-01 module?
A1: The module directly integrates with ABB ACS 300, ACS 400, ACS/ACP/ACF 600, and DCS 500 drive networks using part number 3BHE035093R0001.

Q2: What are the limits for the fiber optic connections on this module?
A2: It requires plastic fiber optic cable (1 mm core diameter) with a maximum distance of 10 meters between sites, maintaining a loss limit under 0.31 dB/m.

Q3: How many drives can the NMBA-01 control simultaneously?
A3: It connects 2 sites in standard setups, but supports between 3 and 248 sites when configured in multi-drive control mode over its 4 Mbit/s DDCS link.
