Product Details

80026-524-01 PM3328B-6-1-3-E Product Description

The ABB PM3328B-6-1-3-E is not a standalone component — it is the foundational power layer that enables every other module in the INFI 90 node to operate within specification. In a fully integrated ABB INFI 90 control architecture, the PM3328B-6-1-3-E supplies regulated multi-rail DC power to the node backplane, ensuring that CPU modules such as the ABB IMMFP12 (Multi-Function Processor) and ABB IMCPM01 (Control Processor Module) receive stable, noise-free power essential for deterministic scan-cycle execution.

On the I/O layer, analog input modules like the ABB IMDSO14 and digital output modules such as the ABB IMASO01 depend on the power supply's ±15 VDC rails for accurate signal conditioning and relay drive. Any voltage ripple or transient at the power supply output propagates directly into signal accuracy — making the PM3328B-6-1-3-E's regulated, low-ripple output a critical specification for process-critical applications in refining, power generation, and chemical processing.

At the communication layer, INFI-NET interface modules including the ABB INNIS21 and ABB INNPM11 (Network Process Module) rely on stable backplane power to maintain continuous peer-to-peer communication across the INFI 90 distributed network. Interruptions at the power layer cascade into communication timeouts, controller failover events, and potential process upsets — underscoring why redundant power supply configurations using a second PM3328B-6-1-3-E in hot-standby mode are standard practice in high-availability plant architectures.

For HMI and operator station integration, the INFI 90 platform connects to ABB OIS40 and ABB OIS42 Operator Interface Stations via INFI-NET. These stations depend on the controller nodes — and by extension the power supply — maintaining continuous uptime. A power supply failure at the node level removes the controller from the network, blinding operators to real-time process data. The PM3328B-6-1-3-E's built-in over-voltage and over-current protection circuits prevent cascading failures that could affect HMI connectivity.

In the execution layer, valve positioners, motor control centers, and variable frequency drives receive setpoint commands from INFI 90 controllers. The ABB IMFEC11 (Field Equipment Controller) and associated I/O marshalling panels depend on the node power supply for uninterrupted output signal generation. For protection-critical loops — such as emergency shutdown (ESD) and high-integrity pressure protection systems (HIPPS) — the power supply's thermal shutdown and short-circuit protection features provide an additional layer of system safety without requiring external protective devices at the module level.

Maintenance engineers working with the INFI 90 platform will recognize the PM3328B-6-1-3-E as a high-priority spare. Its compatibility with the standard INFI 90 node enclosure means replacement requires no backplane modification, no firmware update, and no reconfiguration of connected I/O modules — enabling mean-time-to-repair (MTTR) measured in minutes rather than hours. Paired with ABB IMDSF01 diagnostic modules and the INFI 90 system's built-in self-diagnostics, maintenance teams can verify power supply health during scheduled outages without removing the unit from service.

Power Generation & Utilities: In combined-cycle gas turbine (CCGT) and coal-fired power plants, INFI 90 DCS nodes control boiler combustion, turbine speed governors, and steam header pressure. The PM3328B-6-1-3-E provides the stable backplane power required for continuous turbine protection and load-following control, where any power interruption triggers automatic turbine trip sequences.

Petroleum Refining & Petrochemical: Crude distillation units, catalytic crackers, and hydroprocessing reactors operate under tight temperature and pressure control managed by INFI 90 controllers. The power supply's redundant configuration capability supports the 99.99% uptime requirements typical of refinery DCS specifications, where unplanned shutdowns carry costs measured in hundreds of thousands of dollars per hour.

Water & Wastewater Treatment: Municipal water treatment facilities and industrial effluent systems use INFI 90 for pump sequencing, chemical dosing, and filtration control. The PM3328B-6-1-3-E's universal AC input range (85–264 VAC) accommodates the variable grid quality common in remote pumping stations and treatment facilities, ensuring controller availability regardless of utility supply fluctuations.

Mining & Minerals Processing: Grinding circuits, flotation cells, and thickener control in copper, gold, and iron ore processing plants rely on INFI 90 DCS for continuous process optimization. The power supply's industrial temperature rating (0–55 °C) and robust protection features support operation in the high-dust, high-vibration environments typical of mineral processing facilities.

Pulp, Paper & Packaging: Paper machine control, digester pressure management, and recovery boiler operation in pulp mills demand continuous DCS availability. The PM3328B-6-1-3-E supports hot-standby redundancy configurations that eliminate single points of failure in the power layer, meeting the continuous-process uptime requirements of paper machine drive systems and chemical recovery operations.

Q1: Is the PM3328B-6-1-3-E compatible with all INFI 90 node configurations, and can it be used in a redundant power supply arrangement? Yes. The PM3328B-6-1-3-E is designed for the standard ABB INFI 90 node enclosure and backplane. It supports hot-standby redundant power configurations when a second unit is installed in the redundant power slot of the node chassis. In redundant mode, the standby unit assumes full load within milliseconds of a primary supply failure, with no interruption to controller operation or I/O scanning. No special firmware or configuration is required — redundancy is managed at the hardware level by the node backplane's power arbitration circuitry.

Q2: What pre-shipment testing is performed, and what does the 12-Month Warranty cover? Every PM3328B-6-1-3-E unit shipped by NANKMOS undergoes a full pre-shipment functional test protocol: input voltage sweep across the rated 85–264 VAC range, output voltage verification on all rails (+5 VDC, ±15 VDC) under rated load, ripple and noise measurement, and protection circuit verification (over-voltage, over-current, short-circuit, and thermal shutdown). The 12-Month Warranty covers all manufacturing defects and functional failures under normal operating conditions from the date of shipment. Warranty claims are processed with priority turnaround to minimize plant downtime.

Q3: How quickly can the PM3328B-6-1-3-E be sourced, and what support is available for long-term INFI 90 fleet maintenance? NANKMOS maintains in-stock inventory of the PM3328B-6-1-3-E for immediate dispatch, with standard lead times of 3–7 business days for international shipments. For customers managing large INFI 90 installed bases, NANKMOS offers consignment stock arrangements and scheduled replenishment programs to ensure critical spare availability without tying up capital in excess inventory.
