RB520 3BSE003528R1
Product Name
ABB AC 800M Series RB520 3BSE003528R1 Remote I/O Communication Module (Industrial Distributed Control System High-Speed Data Transmission Dedicated)
(Naming convention explanation for ABB AC 800M modules:
- “RB” = Product function identifier, representing “Remote Bus” — specialized in connecting distributed I/O modules to the AC 800M controller, distinguishing it from local I/O modules (e.g., “DI” for digital input) or CPU modules (e.g., “PM” for process module).
- “520” = Model sequence code: “5” denotes the remote communication product family; “20” specifies Profinet-based remote I/O connectivity (differentiated from “10” series for Modbus-RTU or “30” series for Ethernet/IP).
- “3BSE003528R1” = ABB’s standard part number & revision code: “3BSE” is the prefix for AC 800M system modules; “003528” is the base part number for RB520 models; “R1” indicates Revision 1 (optimized for communication latency and network redundancy).
- Core positioning: Serves as a “remote I/O data gateway” for ABB AC 800M DCS, enabling high-speed data exchange between central controllers (e.g., PM866-2) and distributed I/O racks in large-scale industrial sites (e.g., chemical parks, oil refineries, power plants).)
2. Product Description
The RB520 3BSE003528R1 module is engineered by ABB for industrial distributed control scenarios (e.g., remote monitoring of oil pipeline pressure sensors, distributed temperature collection in chemical plants, power plant auxiliary system I/O connectivity). It addresses key challenges including “long-distance reliable communication, network fault tolerance, and harsh environment adaptability,” with core advantages as follows:
-
Profinet-Based High-Speed Remote ConnectivitySupports Profinet IRT (Isochronous Real-Time) protocol, delivering a data transmission rate of 1Gbps and a minimum cycle time of 1ms — ensuring real-time synchronization between the central controller and remote I/O modules (e.g., DI840 digital input, AI840 analog input). It can connect up to 64 distributed I/O stations per network segment, with a maximum transmission distance of 1000m (via fiber optic cable) or 100m (via Cat5e/Cat6 Ethernet cable), ideal for large sites with scattered I/O points.
-
Dual-Network Redundancy for Fault ToleranceFeatures two Profinet ports (Port 1/Port 2) supporting Media Redundancy Protocol (MRP) and Parallel Redundancy Protocol (PRP). In MRP mode, it switches to the backup network within ≤100ms if the primary network fails; in PRP mode, it transmits duplicate data over two independent networks, ensuring zero data loss during single-network outages. This redundancy eliminates communication-related downtime, critical for safety-critical processes (e.g., chemical reactor emergency shutdown systems).
