Description
Product Introduction
Legacy ABB Advant Master / AC450 DCS systems face communication network failure risks when original LAN interface modules fail. Original factory lead times are extremely long and new production has been discontinued. The ABB CS513 (3BSE000435R1) is an IEEE802.3 MasterBus300 network communication module, designed specifically for Advant Master AC450 controllers. It establishes the core control network link between controllers, operator stations and I/O racks. It helps maintenance teams restore plant control network quickly during shutdowns, avoiding costly full DCS system migration.
3. Key Features & Benefits
MasterBus 300 / MasterBus 300E dual mode selectable: Hardware DIP switch configurable for standard or extended bus mode -> Matches different original Advant network configurations, no program modification required for direct replacement.
IEEE 802.3 coaxial LAN interface, BNC connector: 1.5 Mbps bus speed, up to 500m without repeater -> Stable long-distance transmission in large control rooms, less signal interference for power and chemical plants.
Supports up to 32 nodes per bus segment: Multi-node Advant Master control network architecture -> Build redundant distributed control network for turbine and boiler auxiliary control.
24VDC power supply, low power consumption 0.2kg lightweight board: Designed for Advant controller rack slot installation -> Hot-swap compatible for rack replacement under controlled plant outage windows.
CE certified, industrial temperature range 0~60°C: Rugged board layout for cabinet installation -> Reliable operation in typical plant control cabinet environment.

6. FAQ
Q: Which ABB controller does CS513 3BSE000435R1 fit? A: It is designed exclusively for Advant Master AC450 controller with MasterBus300 network. It cannot work with AC800M / 800xA system.
Q: Can I replace an existing CS513 directly? A: Yes, set the DIP switch to match your original bus mode (MB300 or MB300E), direct plug-in replacement without logic changes.
Q: Is CS513 still produced by ABB? A: This module is obsolete / end of life. Available stock is fully refurbished and pre-tested spare part for legacy system maintenance.
Q: What happens if the MasterBus network fails? A: Faulty CS513 will cut communication between controllers and operator stations, which is a high priority spare for planned outage maintenance.
