Specification |
Manufacturer / Model |
ABB / 3BHL000986P0006 |
Product Type |
Fiber Optic Converter Module |
Compatible Controllers |
AC 800M (e.g., PM861, PM851) |
Form Factor |
S800 I/O Module (to be mounted on an S800 I/O Unit) |
Primary Function |
Electrical-to-Optical (E/O) and Optical-to-Electrical (O/E) signal conversion. |
Supported Protocols |
MasterBus 300 (MB300). This is ABB's proprietary, deterministic communication protocol for controller-to-I/O communication. |
Network Topology |
Redundant, fault-tolerant ring (most common). Also supports linear and star topologies. |
Data Transfer Rate |
1.5 Mbps (Standard Speed for MB300 networks) |
Fiber Type |
Multimode (62.5/125 µm or 50/125 µm) |
Connector Type |
BFOC/2.5 (ST-type) |
Wavelength |
820 nm |
Transmitter Type |
LED |
Maximum Cable Distance |
Approx. 2 km (1.24 miles) between nodes with 62.5/125 µm fiber. |
Optical Budget |
Typically 11 dB (allows for splices and connectors over the cable run). |
Power Supply |
Powered directly from the S800 I/O Unit's backplane (5V DC). |
Isolation |
High-voltage isolation provided by the fiber-optic cable, making it immune to EMI/RFI and ground potential differences. |
LED Indicators |
RUN (Green): Normal operation. COM (Yellow): Communication activity. RX (Red): Receive error/fault. TX (Red): Transmit error/fault. |
Redundancy |
Supports module redundancy (NMR, No-Master-Recovery) when configured in pairs. |
Environmental Conditions |
Operating Temperature: 0°C to +55°C Storage Temperature: -40°C to +70°C Relative Humidity: 5% to 95% (non-condensing) |

Function and Application
Purpose: This module acts as the physical layer interface between the electrical world of the controller's processor and the optical world of the fieldbus network (MasterBus 300).
Noise Immunity: By using fiber optics, it eliminates issues with electromagnetic interference (EMI), radio frequency interference (RFI), and ground loops, which are common in industrial environments with heavy machinery.
Long Distance: Enables communication over much longer distances (up to 2 km) compared to copper-based solutions without repeaters.
Intrinsic Safety: Fiber optics do not carry electrical current, making them ideal for use in hazardous areas.
Security: It is extremely difficult to tap into a fiber-optic cable without detection, providing a more secure data link.
High Availability: It is a key component in building redundant network architectures (rings) where a single cable or module failure will not interrupt the communication between the controller and its I/O modules.
Typical Use Case
The 3BHL000986P0006 is used to connect an AC 800M controller (like a PM861) to a remote S800 I/O rack located in a switchyard, a motor control center (MCC), or another area of the plant that is far from the central control room. The fiber-optic link ensures reliable and fast data transfer across this distance, immune to all the electrical noise present in the industrial environment.
