Country of Origin
This module is engineered and manufactured by ABB in Finland, the global hub for ABB’s high-power drive technology.
Application Fields
The DSMB-01C is essential for decentralized control in large industrial drive configurations:
- Multi-Drive Systems: Distributing control signals from a single AC800M controller to multiple inverter modules.
- Metals Industry: Coordinating synchronized motor movements in rolling mills.
- Pulp & Paper: Managing section drives in large-scale paper machines.
- Marine Propulsion: Connecting central bridge controls to multiple propulsion converters.
- Mining: Driving large conveyor networks and winches where electrical isolation is critical.
Product Usage Instructions
- Mounting: Secure the module onto a standard 35mm DIN rail. Ensure it is placed away from high-heat sources to maintain optimal optical signal integrity.
- Power Supply: Connect a regulated 24V DC supply to the power terminals. Correct polarity is essential for the internal logic to operate.
- Fiber Connectivity: Plug the master fiber cable into the “CH0” (Master) port. Connect individual inverter or follower modules to ports “CH1” through “CH7.”
- Handling Optics: Always use dust caps on unused ports. Clean the ends of the fiber optic cables with a lint-free wipe before insertion to avoid signal attenuation.
- Addressing: The DSMB-01C is a transparent hub; the addressing of individual drives is handled within the drive software/parameters, not on the board itself.
Product Technical Description
Technically, the DSMB-01C is a “Star Coupler.” In large drive systems, the central controller needs to speak to several units simultaneously. Instead of “daisy-chaining” them (which could cause a total system failure if one unit fails), the DSMB-01C allows for a star topology. This provides Galvanic Isolation and ensures that if one fiber link is damaged, the rest of the drive system continues to function. The “C” revision features improved light-emitting diodes (LEDs) for more consistent signal transmission over longer distances.
Q&A (Common Questions)
Q: What is the maximum distance for the fiber optic cables? A: For Plastic Optical Fiber (POF), the maximum distance is typically 15–20 meters. For longer runs (up to 200 meters), Hard Clad Silica (HCS) fibers should be used.
Q: Can I use the DSMB-01C with an ACS580 drive? A: The ACS580 typically uses Ethernet-based communication. The DSMB-01C is specifically for systems utilizing the DDCS protocol, such as the ACS800 and certain ACS880 high-power configurations.
Q: What does it mean if the “Power” LED is on but the drives won’t communicate? A: This usually points to a dirty fiber connection or a “crossed” cable (TX and RX swapped). Ensure that the “Transmitter” at one end is connected to the “Receiver” at the other.
Q: Is the DSMB-01C interchangeable with the DSMB-02? A: No. While they perform similar star-coupler functions, the DSMB-02 has different channel densities and is designed for different hardware families.
