TC-BATT01 Honeywell Backup Battery Module

Overview

The Honeywell TC-BATT01, also cataloged as the TC-BATT01 Backup Battery Module, operates as a dedicated lithium backup power component for non-volatile memory retention and real-time clock operation within Honeywell Experion PKS controller platforms.

Hardware Specifications

Process Control Memory Retention Characteristics

The Honeywell TC-BATT01 provides backup energy for controller memory circuits and clock components when the main system power source is removed. Therefore, the module maintains stored configuration parameters, application logic data, and real-time clock information during planned maintenance or unexpected power interruptions.

For Honeywell process control platforms, the battery module supports stable memory retention functions rather than field signal processing. The module does not provide 4-20 mA HART loop communication or FOUNDATION Fieldbus interface functions because it operates as a dedicated power retention device.

The battery connection uses a polarized plug design, which controls installation orientation and prevents incorrect electrical connection. Additionally, the lithium primary cell construction supports extended storage periods and operation across industrial temperature ranges.

Frequently Asked Questions

Q: Can the TC-BATT01 battery module be recharged during controller operation?
A: No. The TC-BATT01 uses a non-rechargeable lithium primary cell. The module must be replaced after reaching the end of its service life.

Q: Does the TC-BATT01 provide power for Honeywell I/O field circuits?
A: No. The module only supports memory retention and real-time clock operation inside compatible Honeywell controller assemblies.

Q: Can the TC-BATT01 be installed without removing the controller configuration?
A: The battery replacement procedure must follow Honeywell controller maintenance instructions to prevent loss of retained memory data.

Field Installation Guidelines

1. Verify the controller chassis power status before replacing the TC-BATT01 module.
2. Confirm the battery connector orientation before insertion. The polarized connector must engage with the matching controller socket without mechanical force.
3. Install the battery away from high-temperature sources, strong electromagnetic interference areas, and locations with excessive vibration.
4. Maintain proper cable routing to avoid contact with sharp edges, moving components, or high-voltage wiring.
5. Dispose of the removed lithium battery according to applicable industrial battery handling regulations.
6. After installation, verify controller memory retention status and real-time clock operation through the system diagnostic interface.
