Description

Engineered for industrial process control reliability, the Honeywell DC-SCMB02 serves as a dedicated CPU battery backup module within Honeywell control architectures. This module is critical for maintaining system integrity, preventing volatile memory loss, and safeguarding runtime databases during primary power interruptions. By ensuring continuous power to the CPU's memory registers, the DC-SCMB02 enables seamless system recovery and warm-restart capabilities without the risk of configuration data corruption.

The compact design allows for direct integration into control card slots, offering low-power consumption and high-reliability standby operations. It is commonly utilized across various Honeywell distributed control system (DCS) platforms where continuous process monitoring and uninterrupted controller operation are mandatory.

Features

  • Ensures retention of volatile CPU memory, configuration files, and real-time clock data during main power loss.
  • Compact, low-profile form factor for optimized spatial efficiency inside control enclosures.
  • Robust circuit protection to prevent overcharging and electrical feedback.
  • Direct backplane integration for secure and reliable signal path connectivity.
  • Long-life standby performance tailored for continuous-duty industrial environments.

Applications

  • Distributed Control Systems (DCS) processor backup.
  • Continuous process industries such as oil and gas, petrochemicals, and power generation.
  • Data retention systems in automated manufacturing environments.

Installation Guidelines

To ensure proper function and avoid damage to the controller assembly, follow these engineering guidelines during installation:

  • ESD Protection: Always wear a properly grounded electrostatic discharge (ESD) wrist strap before handling the battery backup module.
  • Power Isolation: Power down the associated CPU rack or card cage before inserting or removing the module, unless hot-swap capabilities are explicitly verified for your specific system revision.
  • Orientation: Verify correct alignment of the edge connector pins with the backplane slot to prevent physical damage to the contact fingers.
  • Disposal: Dispose of used batteries or modules in accordance with local environmental regulations regarding lithium/industrial battery waste.
