ABB ICSE08B5 – Uninterruptible Power Supply (UPS) Module

Product Description

The ABB ICSE08B5 is a rack-mountable uninterruptible power supply (UPS) module designed specifically for ABB’s automation systems, such as the Advant Controller Builder (ACB) and MasterPiece 200 series. Its primary function is to provide continuous, regulated, and conditioned DC power to critical controller and communication modules in the event of a main power failure. By integrating the ABB ICSE08B5 into a control system, engineers ensure that the PLC processor, volatile memory, and essential communication links remain powered during short-term outages, preventing uncontrolled shutdowns and loss of process data. The reliability of the entire automation system during power disturbances can depend on the performance of the ICSE08B5.

Product Parameters

• Product Family: ACB/MP200 System Power Module.

• Function: Uninterruptible DC Power Supply with battery backup.

• Input Voltage: Typically accepts a wide-range AC input (e.g., 85-264 VAC).

• Output Voltage: Provides a regulated DC output voltage, commonly +24 VDC, to power the system rack.

• Battery Back-up: Includes connections for external sealed lead-acid (SLA) batteries. The “08” in the part number often denotes an 8 Ampere-hour (Ah) battery capacity recommendation.

• Automatic Functionality: Automatically switches to battery power upon AC input loss and recharges the batteries when AC power is restored.

• Monitoring: Provides status signals (e.g., AC OK, Battery Low, Battery Fault) that can be wired to digital inputs of the PLC for system monitoring and alarm generation.

• Mounting: Designed for mounting on a DIN rail or panel within the system enclosure.

Advantages and Features

• System Integrity Protection: Prevents data corruption in the PLC’s volatile memory and avoids uncontrolled process stops during brief power dips or outages, which is critical for process safety and product quality.

• Conditioned Power: Filters and regulates the incoming AC power, protecting sensitive electronic modules from voltage spikes, sags, and electrical noise present on the mains supply.

• Seamless Integration: Designed to fit electrically and mechanically within the ABB ACB/MP200 system architecture, with compatible connectors and voltage levels for the backplane.

• Supervisory Capability: The available alarm contacts allow the PLC program itself to be aware of a power failure and battery status, enabling orderly shutdown procedures for extended outages.

• Maintenance Features: Often includes a battery test function to verify the health and capacity of the connected backup batteries.

• Proven Reliability: As a genuine ABB system component, it ensures compatibility and reliability, which is essential for the overall availability of the control system.

Application Cases in Various Fields

• Continuous Process Industries (Chemicals, Pharmaceuticals): Protects batch recipes and process parameters in the controller memory during momentary grid disturbances, preventing costly batch losses or safety incidents.

• Water and Wastewater Management: Ensures that pumping stations and treatment processes maintain control during short power interruptions, preventing overflow or process upsets.

• Power Generation Plants: Provides ride-through power for critical auxiliary system controllers during switchgear operations or grid transients that cause brief voltage dips.

• Manufacturing with Robotic Cells: Prevents robots from faulting and requiring re-homing due to a brief power blink, minimizing production line downtime.

• Oil & Gas Remote Installations: Where power quality can be poor, it conditions the supply and backs up the control system for remote wellhead or compressor control.

Comparisons with Competing Products

Competing products include generic industrial 24VDC UPS units from manufacturers like SolaHD, PULS, or Phoenix Contact. The primary advantage of the ABB ICSE08B5 is its specific design and validation for the ACB/MP200 system. While a generic UPS may provide similar voltage, it may lack the specific form factor, monitoring signal compatibility, or guaranteed inrush current handling for the ABB backplane. Using the ICSE08B5 ensures a known, tested performance envelope and simplifies system engineering and spare parts management for the legacy ABB platform.

Selection Suggestions and Precautions

• System Power Budget: Calculate the total DC current consumption of all modules in the rack (CPU, I/O, communication) to ensure the ICSE08B5‘s output current rating is sufficient, including any inrush currents.

• Backup Time Requirements: The “08” indicates a typical battery size (8Ah). Determine the required ride-through time and size the external batteries accordingly. Larger batteries can be connected for longer backup durations.

• Battery Maintenance and Replacement: Sealed lead-acid batteries have a finite life (typically 3-5 years). Establish a scheduled replacement program. Always replace batteries with the correct voltage and Ah rating.

• Alarm Integration: For full system awareness, wire the ICSE08B5‘s “Battery Low” and “AC Fail” alarm contacts to digital inputs on the PLC and program appropriate alarm responses (e.g., initiate a controlled shutdown).

• Environmental Conditions: Install the UPS and batteries in an environment within their specified temperature range. High temperatures significantly reduce battery life.

• Safety First: When replacing batteries, follow electrical safety procedures. Batteries can deliver high short-circuit currents. Ensure correct polarity during connection.

• Testing Procedure: Periodically test the UPS function by simulating a mains power failure (disconnect AC input) and verifying the system remains operational for the expected duration.
