TC-BATT01 | Honeywell | Backup Battery Module

The Honeywell TC-BATT01, also cataloged as the TC-BATT01 Backup Battery Modules, operates as a dedicated hardware component for non-volatile RAM retention and system RAM voltage maintenance within Honeywell TDC 3000 and Experion PKS platforms.

Hardware Specifications

Channel-to-Channel Isolation & Cold Junction Compensation (CJC) Coexistence

The TC-BATT01 module supplies regulated backup voltage directly to the controller backplane memory bus to prevent loss of volatile configuration parameters during system power interruptions. Operating alongside analog field I/O interfaces, the module maintains electrical decoupling from analog loop circuitry. This prevents potential ground loop currents or external noise propagation across adjacent channels that utilize the 4-20 mA HART loop protocol or low-voltage thermocouple signals relying on cold junction compensation (CJC).

Frequently Asked Questions

Q: What is the primary functional role of the TC-BATT01 module within the controller rack?

A: The module supplies dedicated backup power to retain volatile controller memory and runtime configuration data during primary AC/DC power failures.

Q: Is the internal battery cell assembly of the TC-BATT01 rechargeable?

A: Yes, the unit utilizes an industrial-grade rechargeable cell architecture that charges automatically from the backplane power supply during normal operation.

Q: Can the TC-BATT01 be replaced without causing loss of controller memory during normal system operation?

A: Yes, when primary system power is energized and stable, replacing the battery module will not corrupt stored memory or interrupt controller execution.

Field Installation Guidelines

1. Slide the TC-BATT01 module into its designated slot within the controller rack chassis until the mechanical locking latch engages fully.
2. Confirm that primary power to the chassis is active prior to replacing an expired module to maintain continuous memory preservation.
3. Ensure cabinet ambient temperatures remain strictly within the specified -20 to +60 deg C operating range to preserve battery shelf life.
4. Route field signal cabling away from the battery module slot to prevent mechanical interference with module extraction levers.
