Product Details
Product Description
The TC-BATT03 (51199942-300) is a high-capacity backup power assembly specifically engineered for the Honeywell Experion PKS C300 controller series. Unlike standard lithium primary cells, this module utilizes Nickel Metal Hydride (NiMH) chemistry to provide a rechargeable, long-duration energy reserve for the controller's volatile memory and real-time clock. This assembly is a critical system component, ensuring that in the event of a total power loss, the C300 processor retains its control strategy, IP configuration, and historical data buffers for a seamless recovery.

Battery Management and System Integrity
The TC-BATT03 (51199942-300) is designed to be charged directly by the C300 controller hardware during normal operation. The 2200 mAh capacity provides a significantly longer backup window than earlier controller generations, which is vital for facilities located in regions with unstable power grids. To maintain the 3.6 VDC nominal output and overall cell health, the Honeywell system performs periodic battery health checks. Engineers should replace this assembly immediately if the "Battery Low" or "Battery Fault" status is reported in the Experion System Management Console to prevent data corruption during an unplanned outage.
Frequently Asked Questions
-
Is this battery hot-swappable?
Yes, the TC-BATT03 is designed to be replaced while the C300 controller is powered and operational. This ensures the backup circuit is never interrupted while the main power is present.
-
How often should this NiMH assembly be replaced?
Under standard operating temperatures, these batteries typically have a service life of 3 to 5 years. However, high-temperature environments in control cabinets may accelerate the aging process, necessitating more frequent replacement.

Tech & Buying Guide
Hub vs Switch vs Router in Industrial Automation Architecture
Modern factory automation relies on reliable industrial networking infrastructure to exchange real-time field data across operational technology systems. Engineers often encounter networking hardware like hubs, switches, and routers when integrating Programmable Logic Controllers, Distributed Control Systems, and SCADA monitoring nodes. Although these devices share physical ports, they operate at different layers of the Open Systems Interconnection reference model and deliver distinct traffic management capabilities.
Marshalling Cabinet Preventive Maintenance: Essential Healthiness Checks for PLC, DCS, and ESD Systems
Marshalling cabinets serve as the vital interface between field instrumentation and control room electronics in modern process facilities. Regular preventive maintenance of these cabinets ensures signal integrity across programmable logic controllers (PLCs), distributed control systems (DCS), and emergency shutdown (ESD) networks. System technicians must execute structured inspection protocols to mitigate environmental risks, identify loose wiring, and maintain continuous operational readiness.
Spatial Computing in Industrial Automation: Elevating PLC and DCS Operations with AR and VR
Industry 4.0 integrates digital intelligence into field operations, transforming factory automation landscapes worldwide. Spatial technologies—specifically Augmented Reality (AR) and Virtual Reality (VR)—redefine how engineers interact with industrial control systems. By bridging computer-generated CAD models with real-time operational technology (OT) data, immersive displays enable intuitive monitoring, rapid diagnostics, and safer maintenance across complex processing facilities.
