Honeywell 30735857‑005 Memory Board
Here is an 800‑word English overview of the Honeywell 30735857‑005 Memory Board, including product details, an industry news update, and information on Guangzhou Qiming Automation Technology Co., Ltd.
Product Overview
The Honeywell 30735857‑005 Memory Board is a critical module for Honeywell’s TDC3000 and Experion PKS distributed control systems. It offers both SRAM and flash storage to hold firmware, configuration data, and historical process values. The board uses industrial‑grade components and a multilayer PCB layout to ensure reliable operation in harsh environments. It mounts easily into the system backplane and begins an automatic self‑test and initialization on power‑up. A backup lithium battery or supercapacitor keeps the SRAM contents intact during power loss, so key data is never lost. Front‑panel LEDs clearly show power status, memory access, and any fault conditions.
Engineers favor the 30735857‑005 because it combines data integrity, ease of maintenance, and long life. Its design life exceeds 10 years when operated within the specified temperature and humidity ranges. Technicians can perform a board swap in minutes without shutting down the entire control system. This hot‑swap capability helps keep critical production lines running. The board’s firmware version is clearly marked on the silkscreen, so users can match it to their software release and avoid compatibility issues.

Key Features and Benefits
- Data Integrity
The board pairs volatile SRAM with non‑volatile flash memory. Critical data is written to flash to survive power cycles. This dual‑memory design ensures that process history and configuration settings remain safe under all conditions. - Rapid Maintenance
A hot‑swap capable connector allows field technicians to replace the board without shutting down the control system. This feature minimizes downtime and keeps production moving. - Robust Design
The multilayer PCB and industrial‑grade components deliver strong resistance to vibration, thermal stress, and electromagnetic interference. The board meets or exceeds Honeywell’s stringent quality tests. - Clear Diagnostics
Front‑panel LEDs provide simple, real‑time feedback on board health. A green LED shows normal power, a yellow LED pulses during memory access, and a red LED lights on fault. This visual reporting speeds up troubleshooting. - Long Service Life
With a design lifespan of over 10 years in standard industrial environments, this board reduces the need for frequent upgrades. Users benefit from a low total cost of ownership.
Recent Industry News
In recent months, leading power generation and chemical processing plants have accelerated their digital transformation efforts. A major petrochemical complex in eastern China completed a control system upgrade that replaced legacy memory and logic boards with modern Honeywell modules like the 30735857‑005. By integrating these new boards with an advanced historian and cloud analytics platform, the plant now tracks critical variables—such as reactor temperature and compressor speed—at one‑second intervals. This high‑resolution data feeds predictive maintenance algorithms that forecast equipment issues days before they occur. Since going live, the facility reports a 30% drop in unplanned shutdowns and a 7% increase in overall equipment effectiveness. Industry experts say such projects mark a shift from reactive to proactive operations and set a new standard for process reliability.
