Module d'extension de batterie Honeywell TK-PPD011 C200

Description

The TK-PPD011 is a hardware support component functioning as a Battery Extension Module (BEM) within the Honeywell C200 and Experion distributed control system (DCS) infrastructure. This auxiliary module provides secondary power preservation capabilities by housing rechargeable energy cells that interface directly with control processors or memory elements. By delivering regulated holdup voltage during primary power interruptions, it extends volatile memory retention time beyond standard onboard limits, preventing the erasure of critical application databases, system logic configurations, and runtime variables. The hardware integrates seamlessly into standard chassis slots, drawing precise operating current from the internal backplane logic rails while regulating trickle-charge parameters to maintain long-term standby readiness.

Features

• Secondary energy storage capacity extending system memory retention parameters.
• Internal trickle-charging circuitry powered via system backplane rails.
• Standard physical form factor allowing adjacent mounting to control processors.
• Low active electrical current consumption profile.

Applications

• Volatile memory preservation in central process controller chassis.
• Non-volatile data backup assurance in critical chemical processing units.
• Extended system holdup protection within power generation automation layers.
• Data integrity security for offshore oil and gas process loops during main power transfer cycles.

Technical Specifications

Installation Guidelines

Grounding and Shielding

Verify that the host chassis rack is bonded to the main plant instrumentation grounding network via a solid, low-impedance copper bus structure. Clean all structural rails thoroughly before fastening hardware to ensure proper surface ground continuity.

Handling and ESD Protection

The electronic sub-assemblies inside this unit are sensitive to static electricity. Technicians must wear an approved, properly bonded static-dissipative wrist strap before picking up the hardware, managing rack insertion, or completing routine cell maintenance.

Insertion and Alignment

Ensure the upper and lower plastic guide tracks of the chassis are aligned with the module card edge. Push the hardware into the assigned slot firmly until the backplane connectors seat completely, and hand-tighten the integrated mechanical retention fasteners to prevent displacement under vibration.

Initial Charging Period

Upon initial installation or module replacement, allow the system backplane to supply continuous trickle-charge current to the unit for the OEM-specified duration to guarantee that full backup lifecycle capacity is available before active power monitoring loops rely on the hardware.

FAQ

What is the core purpose of this hardware in a control rack?

It provides auxiliary backup energy to extend the retention timeframe of volatile memory systems inside adjacent control processors during main power losses.

Does this hardware provide power to the field-side input/output loops?

No, it is strictly designed to sustain logic or memory registers within the controller rack backplane and does not supply field device loops.

What current does the module draw from the 24 VDC backplane rail?

The continuous current consumption from the 24 VDC supply rail is specified at 0.036 A.

What is the current demand of the unit from the 5 VDC logic rail?

The module draws a steady-state current of 0.112 A from the 5 VDC backplane logic rail.

Are the internal battery cells rechargeable in this extension module?

Yes, the hardware uses rechargeable elements that leverage internal charging infrastructure powered directly by the backplane.

Can this unit be located in any open slot within the controller chassis?

It is typically mounted in specific slots designated next to the primary control processor module as outlined in system architecture engineering docs.

What is the net weight of the standalone module assembly?

The physical module has a net unboxed weight of exactly 0.36 Kg.

How does the unit prevent overcharging during continuous operation?

The internal circuitry regulates current and monitors charge states to switch to trickle mode once full standby capacity is realized.

What steps are needed to secure the hardware against mechanical vibration?

The module features integrated top and bottom mounting tabs that must be bolted securely to the standard chassis faceplate.

Should the module be placed in anti-static storage when not in service?

Yes, always store and transport the assembly inside an approved anti-static ESD shielding bag when it is removed from the active rack.
