Bailey INFI 90 PM3328B Series Technical Notes

Due to the long operational lifecycles typical of DCS installations — often 20 to 30 years — PM3328B series components remain in active demand for maintenance, repair, and overhaul (MRO) programs at facilities that have not yet migrated to ABB's successor platforms (System 800xA). DriveKNMS maintains a dedicated inventory of PM3328B series modules to support these long-term operational commitments.

The Evolution of PM3328B Architecture

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

PM3328B Full Catalog & Functionalities (SKU List)

The following SKUs represent verified, commonly sourced models within the Bailey INFI 90 PM3328B power supply and associated module range. Each entry reflects a distinct hardware configuration or output specification.

80026-524-01 PM3328B-6-1-3-E: INFI 90 regulated DC power supply module, 6A output, single-feed configuration, revision E — primary listing for this product page.

PM3328B-6-2-3-E: Dual-feed input variant; supports redundant AC source switching for high-availability cabinet configurations.

PM3328B-3-1-3-E: 3A output variant; used in smaller MMU configurations with reduced I/O module count.

PM3328B-3-2-3-E: 3A output, dual-feed input; redundant power architecture for critical process loops.

PM3328B-12-1-3-E: 12A high-current output variant; deployed in fully populated MMU cabinets with dense I/O loading.

PM3328B-12-2-3-E: 12A output, dual-feed; maximum capacity redundant power supply for large INFI 90 cabinets.

80026-524-02: Alternative part number cross-reference for PM3328B power supply assembly; verify exact suffix before substitution.

PM3328A-6-1-3: Predecessor series to PM3328B; mechanically compatible but electrically distinct — not a direct drop-in replacement without engineering review.

PM3328C-6-1-3-E: Successor variant with updated internal switching topology; backward-compatible with INFI 90 MMU backplane.

IMFEC11: INFI 90 Field Interface Module — frequently co-sourced with PM3328B power supplies during cabinet refurbishment projects.

IMASI23: Analog Signal Input module; standard I/O module powered by PM3328B supply rails in INFI 90 MMU configurations.

IMASO11: Analog Signal Output module; 4–20 mA output card operating on INFI 90 DC bus supplied by PM3328B.

IMDSI22: Digital Signal Input module; 32-channel DI card for discrete process monitoring in INFI 90 systems.

IMDSO14: Digital Signal Output module; 16-channel DO card for valve and actuator control in INFI 90 cabinets.

IMMFP12: Multi-Function Processor module; INFI 90 controller card that draws regulated power from PM3328B supply modules.

IMCPM12: Communication Processor Module; handles peer-to-peer and host communication on the INFI 90 Plant Loop network.

NTMP01: Module Mounting Unit (MMU) termination panel; the physical backplane into which PM3328B and I/O modules are installed.

Sourcing Hard-to-Find & Obsolete PM3328B Parts

The PM3328B series is classified as end-of-life by ABB. Original equipment manufacturer (OEM) support for new unit procurement has been discontinued. DriveKNMS operates a dedicated procurement and refurbishment program for INFI 90 PM3328B modules, sourcing units from decommissioned plant equipment, controlled surplus inventories, and authorized refurbishment channels.

Quality Control for the PM3328B Range

Power supply modules within the PM3328B series present specific test challenges due to their role as the primary power source for all downstream INFI 90 modules on the MMU backplane. DriveKNMS applies the following test protocol to all PM3328B units:

Input voltage range verification: Confirm correct operation across specified AC input range (typically 100–240 VAC, 47–63 Hz) per module nameplate data.

Output voltage regulation test: Measure DC output voltage at no-load, 50% load, and full-rated load conditions. Verify regulation within ±1% of nominal.

Ripple and noise measurement: Oscilloscope measurement of output ripple voltage under full load. Reject units exceeding OEM-specified ripple limits.

Capacitor ESR measurement: Electrolytic capacitor equivalent series resistance (ESR) measurement to identify aged or degraded filter capacitors — a primary failure mode in long-service PM3328B units.
