Yokogawa SPW482 Series Technical Notes

SPW482 Full Catalog & Functionalities (SKU List)

The following SKUs represent the verified SPW482 series and closely associated CENTUM VP power infrastructure modules. Each entry reflects a distinct hardware configuration or output specification.

Power Supply Modules — SPW482 Series

• SPW482-E3 S1: 24 VDC single-output power supply module, E3 hardware revision, standard FCS backplane fit
• SPW482-E3 S2: 24 VDC dual-output configuration, supports split-bus redundancy on expanded FCS chassis
• SPW482-E2 S1: Previous E2 hardware revision, single output; functionally equivalent to E3 S1, PCB-level component differences
• SPW482-E1 S1: Original E1 release; compatible with CS 3000 R3.x and CENTUM VP R4.x and later
• SPW481-E3 S1: Predecessor series; single-output, narrower AC input range (100–240 VAC), CS 3000 primary platform
• SPW481-E2 S1: CS 3000 era power supply, E2 revision; widely deployed in pre-2008 installations still in service

• CP345-1: CS 3000 FCS CPU module; legacy platform, widely maintained in brownfield sites

Analog Input (AI) Modules

• AAI141-S00: 16-channel 4–20 mA analog input, HART-enabled, standard isolation
• AAI143-S00: 16-channel AI with enhanced HART pass-through and channel-to-channel isolation
• AAI841-S00: 8-channel high-accuracy AI, ±0.1% span, for precision measurement loops

Analog Output (AO) Modules

• AAO141-S00: 8-channel 4–20 mA analog output, HART-enabled, FCS backplane mount
• AAO841-S00: 4-channel high-accuracy AO, ±0.1% span, for critical final control elements

Digital Input / Output (DI/DO) Modules

• ADV151-P00: 32-channel 24 VDC digital input module, sink type
• ADV551-P00: 32-channel 24 VDC digital output module, source type, 0.5 A per channel
• ADV161-P00: 64-channel DI, high-density configuration for large I/O node installations

Communication & Network Modules

• ALR111-S00: Vnet/IP communication module, dual-port redundant Ethernet, FCS integration
• AER111-S00: FOUNDATION Fieldbus H1 interface module, 4-segment capacity

Quality Control for the SPW482 Range

Power supply modules present specific test challenges due to their role as the primary energy source for entire FCS backplane assemblies. DriveKNMS applies the following test protocol to all SPW482 units prior to dispatch:

• Input voltage sweep test: Units are energized across the full rated AC input range (85–264 VAC) to verify regulation performance at voltage extremes.
• Output load regulation test: 24 VDC output is measured under 0%, 50%, and 100% rated load conditions. Voltage must remain within ±1% of nominal.
• Redundancy switchover simulation: Where a paired redundant unit is available, automatic switchover is triggered and transfer time is measured against Yokogawa's specification of <20 ms.
• Thermal burn-in: Units are operated at full load for a minimum of 8 hours in a temperature-controlled environment to screen for infant mortality failures.
• Backplane communication verification: Module is seated in a CENTUM VP-compatible test chassis and self-diagnostic status is confirmed via the FCS engineering tool.
• Visual and component inspection: PCB-level inspection for capacitor bulge, solder joint integrity, and corrosion on connector pins.
