Plants running N-90, INFI 90 or Harmony controllers rarely get a budget to replace the whole cabinet. The SPBRC410 removes the need to try: it occupies the same Harmony slot as a BRC-400 or HPG-800, runs the existing I/O modules and terminal units unchanged, and adds what the old bridge controllers never had — an onboard Ethernet port speaking Modbus TCP to PLCs, smart instruments and SCADA.

Mechanically, nothing: same mounting unit, same connectors, same wiring. What changes is the processor (a 32-bit Freescale ColdFire at 160–256 MHz, more than ten times faster than the controllers it replaces), the strategy headroom (30,000 function blocks, block addresses beyond 10,000, roughly 2,000 closed-loop I/O points), and the communications path to third-party equipment, which moves from optional add-on cards to a port that is already on the module.
Capacity and Communications
| Processor | 32-bit Freescale ColdFire MCF5475 at 160–256 MHz — more than 10× the previous generation |
| Memory | 4 MB ROM, 64 MB RAM, 2 MB NVRAM (strategy and configuration survive a power failure) |
| Function blocks | Up to 30,000, with block addresses beyond 10,000 |
| I/O capacity | About 2,000 points closed-loop; up to 64 Harmony rack-mounted I/O modules locally |
| Ethernet | 1 × 10/100 Mbps TCP/IP |
| Modbus TCP | Master and slave; up to 4,000 bidirectional data points; up to 50 third-party PLCs |
| Serial | 2 × RS-232 (Modbus RTU/ASCII and Allen-Bradley DF1 via the GPI option) |
| Continuous, sequential, batch | All supported on one controller |
Redundancy and Installation
For control loops that cannot tolerate a single point of failure, two SPBRC410 modules form a 1:1 hot standby pair over the RRI synchronisation link: both controllers execute the same strategy in real time and failover is disturbance-free. Installation follows Harmony practice — the module fits a standard IEMMU21 slot, is hot-swappable, and draws 1.05 A / 5.25 W (maximum 1.25 A) from the +5 VDC backplane. Engineering is done in Composer / S+ Engineering; device integration through the GPI option needs firmware revision M_0 or later, and note that GPI and Harmony Gateway Software (HGS) cannot run in the same controller. Dimensions are 254 × 203.2 × 101.6 mm at about 0.75 kg, rated 0 to +70 °C with forced cabinet ventilation.
Before You Order
The SPBRC410 is at work in power generation, water treatment, oil and gas, and pulp and paper plants — anywhere an INFI 90 era cabinet needs third-party integration or a staged path into Symphony Plus.
