Product Details
The Honeywell 900K01-0201, also cataloged as the 900K01 Battery Module Assembly, operates as a dedicated hardware component for backup power delivery to volatile memory components within Honeywell ControlEdge HC900 controller platforms. Operating at a 5 VDC backplane logic level with a maximum current draw of 17 mA, the module installs directly into the controller slot or dedicated power housing. It maintains real-time clock (RTC) synchronization and preserves dynamic RAM registers during main system power outages.

Process Control Integration & DCS Field Interfacing
The Honeywell 900K01-0201 ensures continuous retention of user program logic, force tables, and historical process trends stored in volatile controller memory when external AC/DC input power is removed. By preventing memory corruption during power cycles, the module supports seamless process restarts without requiring cold-boot initialization or logic reloading from supervisory DCS control networks. This memory retention maintains system readiness for analog interface cards managing 4-20 mA HART loop protocol field instruments.
Frequently Asked Questions
Q: What is the primary electrical requirement for the 900K01-0201 module backplane interface?
A: The module operates on a 5 VDC logic bus rail and draws a maximum current of 17 mA during active backplane operation.
Q: What happens to the HC900 controller if the 900K01-0201 backup assembly is depleted during a power outage?
A: If depleted during an extended power outage, un-backed volatile RAM registers may reset, requiring system configuration and clock settings to be restored from non-volatile flash memory upon power restoration.
Field Installation Guidelines
- Ensure the controller slot or battery retention housing is free of debris before inserting the 900K01-0201 assembly.
- Handle the module using anti-static wrist straps to prevent electrostatic discharge (ESD) damage to sensitive backplane contacts.
- Verify correct keying and mechanical orientation prior to pushing the module into the backplane connector.
- Maintain ambient panel operating temperatures between 0 and +60 deg C to optimize backup cell longevity and prevent accelerated self-discharge.

Tech & Buying Guide
Understanding Modern SCADA Systems: Architecture, Communication Topologies, and Industrial Applications
Supervisory Control and Data Acquisition (SCADA) systems form the digital backbone of modern industrial automation. They collect critical field data, transmit signals across vast distances, and empower plant operators with real-time process visibility. Across modern infrastructures, SCADA solutions streamline centralized control and maintain continuous operational uptime.
Understanding OPC Servers in Modern Industrial Automation: Principles, Architecture, and Applications
In industrial automation, connecting physical hardware with high-level software remains a primary operational challenge. Factories utilize programmable logic controllers (PLCs), distributed control systems (DCS), human-machine interfaces (HMIs), and smart sensors from diverse vendors. These devices often speak different proprietary protocols. Open Platform Communications (OPC) servers solve this interoperability challenge by standardizing how data flows across factory networks.
Industrial Fiber Optic Cables: Principles, Connectors, and Fusion Splicing Techniques
Modern factory automation relies heavily on fiber optic cables for high-speed industrial data transmission. Fiber optic cables transmit light pulses instead of electrical signals, eliminating electromagnetic interference (EMI) risks completely. Each optical strand consists of a high-purity glass core surrounded by a protective cladding layer. The difference in refractive index between core and cladding enables total internal reflection. Protective resin buffers, Kevlar strength members, and rugged outer jackets safeguard delicate glass cores in harsh environments. Consequently, automation engineers prefer fiber backbones for reliable noise-free communication in industrial control systems.
