ABB Harmony BRC Bridge Controller
The ABB Harmony BRC Bridge Controller family includes SPBRC300, SPBRC400 and SPBRC410, which are designed for ABB Harmony Rack industrial control system applications. These controllers form part of ABB’s established Harmony Rack controller architecture and provide control processing together with support for multiple generations of ABB I/O.
ABB documentation identifies SPBRC300, SPBRC400 and SPBRC410 as members of the Harmony Rack BRC controller family. The controllers support HR Series I/O, including previous rack generations, as well as SD Series I/O, Block I/O and S800 I/O. SD Series support includes technologies such as PROFIBUS and HART I/O.

Available ABB BRC Models
This product page covers the following three Harmony Rack BRC models:
ABB SPBRC300 – BRC300 Bridge Controller
SPBRC300 is part of the ABB Harmony Rack BRC controller family. The BRC300 is designed for process control applications within the Harmony architecture and provides compatibility with established Harmony Rack system infrastructure.
Customers searching for ABB BRC300 may also encounter the complete Harmony Rack ordering designation SPBRC300. For quotation purposes, the complete part number shown on the existing controller should always be verified.
ABB SPBRC400 – BRC400 Bridge Controller
SPBRC400 represents the BRC400 member of the Harmony Rack BRC family. It supports the established Harmony control architecture and multiple ABB I/O families.
ABB documentation groups SPBRC400 together with SPBRC300 and SPBRC410 as Harmony Rack BRC controllers. ABB Library
When replacing an existing BRC400 controller, customers should provide the complete product number and, where possible, a clear photograph of the existing module label.
ABB SPBRC410 – BRC410 Bridge Controller
SPBRC410 is the BRC410 member of the Harmony Rack BRC family and adds capabilities beyond earlier BRC generations.
ABB states that the BRC410 provides enhanced online configuration and MODBUS TCP support. ABB documentation specifies support for up to 30,000 block addresses and 4,000 MODBUS TCP/IP points. ABB Library
A separate ABB BRC410 data sheet specifies a 160 MHz ColdFire MCF5407 processor, 8 MB DRAM, 2 MB NVRAM and a 10/100 Mbps RJ45 Ethernet connection. It also documents optional redundancy through an RCL cable connection. ABB Library
SPBRC300 vs SPBRC400 vs SPBRC410
| Model | Controller | Family | MODBUS TCP |
|---|---|---|---|
| SPBRC300 | BRC300 | Harmony Rack BRC | — |
| SPBRC400 | BRC400 | Harmony Rack BRC | — |
| SPBRC410 | BRC410 | Harmony Rack BRC | Yes |
ABB specifically states that MODBUS TCP devices are supported through the BRC410 only within this BRC300/400/410 grouping. ABB Library
This is an important distinction when selecting a controller. Customers requiring MODBUS TCP connectivity should not assume that SPBRC300, SPBRC400 and SPBRC410 provide identical communication capabilities.
Harmony Rack I/O Support
One of the important characteristics of the ABB BRC controller family is its ability to work with multiple ABB I/O architectures.
ABB documentation states that these Harmony Rack BRC controllers provide simultaneous support for:
Harmony Rack HR Series I/O, including previous rack generations; SD Series I/O, including PROFIBUS and HART I/O support; Block I/O; and S800 I/O. ABB Library
This makes the BRC family relevant to installed ABB control systems where existing I/O infrastructure must be maintained while controllers or other system components are serviced or replaced.
Applications of ABB BRC Controllers
ABB Harmony BRC controllers are intended for industrial process control applications using the Harmony Rack architecture.
Typical requirements can include maintenance of existing ABB control systems, replacement of installed BRC controllers, plant shutdown maintenance, control system refurbishment, modernization projects and stocking critical automation spare parts.
Because ABB control systems can remain in industrial service for many years, accurate model identification is important.
Customers should verify whether the installed controller is SPBRC300, SPBRC400 or SPBRC410 before requesting a replacement.
How to Select the Correct BRC Controller
Start by checking the identification label on the existing controller.
If the installed module is labeled SPBRC300, select SPBRC300.
If the installed module is labeled SPBRC400, select SPBRC400.
If the installed module is labeled SPBRC410, select SPBRC410.
Customers requiring the Ethernet and MODBUS TCP functionality documented for BRC410 should pay particular attention to the controller version. ABB’s documentation specifically associates MODBUS TCP capability with BRC410. ABB Library
Do not select a replacement solely according to the physical appearance of the module. The complete ABB part number and system requirements should be confirmed.
BRC410 Performance and Communication
The BRC410 introduced additional capabilities within the BRC family.
ABB describes the BRC410 as supporting up to 30,000 function blocks and documents Ethernet and MODBUS TCP capabilities. ABB’s BRC410 technical material also states that the controller uses the same function codes as BRC300 and BRC400. ABB Library
This allows the product to serve applications requiring established Harmony control functionality together with additional communication capabilities.
