Product Details

Product Description

The TC-BATT01 is a high-performance lithium primary cell engineered specifically for the Honeywell PLC and Experion controller series. Its primary function is to provide non-volatile memory (RAM) backup, safeguarding critical configuration data and user programs during main power interruptions. This industrial-grade cell is characterized by its stable discharge curve and long shelf life, ensuring that automated systems can recover seamlessly without loss of operational logic.

Technical Specifications

  • Module Identification: TC-BATT01

  • Chemical Composition: Lithium (Non-Rechargeable)

  • Nominal Output: 3.0 Vdc

  • Rated Capacity: 1700 mAh

  • Internal Protection: Integrated safety current limiting to prevent thermal runaway

  • Connector Type: Application-specific polarized connector for secure installation

  • Storage Life: Up to 10 years (at 20°C ambient)

  • Dimensions: 3.4 cm (H) x 1.7 cm (W) x 1.7 cm (D)

  • Net Weight: 0.068 kg

  • Deployment Scope: Honeywell Industrial Automation and Process Control Platforms

Application Maintenance

The TC-BATT01 is typically located within the controller chassis or processor module. To maintain system integrity, engineers should monitor the "Low Battery" diagnostic flag within the controller software. It is recommended to replace these cells during scheduled preventive maintenance cycles to avoid unplanned downtime or memory corruption in the event of a facility-wide power loss.

Frequently Asked Questions

  • Can this battery be replaced while the controller is powered?

    Yes, for most Honeywell systems, replacing the TC-BATT01 while the rack is powered prevents memory loss during the swap. Always refer to your specific controller hardware manual for safety procedures.

  • Is this battery compatible with generic 3V lithium cells?

    While the chemistry may be similar, the TC-BATT01 features a specialized housing and terminal connector tailored to Honeywell hardware specifications to ensure physical fit and electrical reliability.

Understanding Root Causes of Unplanned PLC Stop Mode in Industrial Automation

Understanding Root Causes of Unplanned PLC Stop Mode in Industrial Automation

Modern Programmable Logic Controllers manage execution through distinct operational states: Run, Stop, Start-Up, and Hold. During power-up, a controller initializes memory registers within Stop mode before briefly transitioning to Start-Up mode. During this phase, internal self-diagnostics evaluate system integrity across hardware and user programs. If the controller detects no critical faults, it enters Run mode to execute the control program continuously. However, any severe system anomaly forces the CPU back into Stop mode immediately to prevent erratic machine behavior across the plant floor.

Human-Machine Interface Design: Essential Guide to HMI Selection, Visualization, and Control System Integration

Human-Machine Interfaces (HMIs) serve as the primary operational window into complex industrial automation systems. Modern HMIs convert raw machine data into clear graphical displays, enabling operators to oversee entire manufacturing processes in real time. Instead of relying on physical control panels full of hardwired switches, engineers program interactive screens using intuitive graphics, dynamic color coding, and responsive touch interfaces. Over my 15 years in control systems engineering, I have observed HMIs transform from basic display screens into sophisticated command centers that drive operational efficiency across DCS and PLC environments.

Understanding Safety Relays in Industrial Automation: Architecture, Operation, and Functional Safety

Understanding Safety Relays in Industrial Automation: Architecture, Operation, and Functional Safety

Standard electromechanical relays provide basic electrical isolation between low-voltage control circuits and high-power output loads. A traditional switching relay features a magnetic coil driving mechanical Common (COM), Normally-Open (NO), and Normally-Closed (NC) contacts. However, standard relays pose severe functional risks when deployed in critical safety interlock circuits. High current inrush or mechanical wear can weld contacts together permanently. If contact welding occurs in an emergency stop circuit, pressing the button fails to halt hazardous machinery movements. Consequently, global functional safety standards prohibit standard relays for critical machine guarding functions.
