Shopify Product Title:

Honeywell 51202306-005 AC Input Filter Module | EMI/RFI Noise Suppression for TDC 3000 & Experion HPM/ APM

Product Description:

The Honeywell 51202306-005 is a highly effective AC Input Filter Module designed to ensure stable and clean power supply to Honeywell TDC 3000 and Experion PKS (Process Knowledge System) controllers. Positioned as the first line of defense in the power distribution system, this module mitigates electromagnetic interference (EMI) and radio frequency interference (RFI), providing critical protection for sensitive electronics inside I/O modules and processors.

This filter module is commonly installed in the HPM (High-Performance Process Manager) and APM (Advanced Process Manager) cabinets, where it serves to prevent harmful power surges or electrical noise from compromising the performance and reliability of the control system. By ensuring that the power entering the system is clean and stable, it helps avoid potential system resets, data corruption, or component failures.

Key Features & Functions:

1. EMI and RFI Filtering:

• The 51202306-005 uses an advanced combination of inductors and capacitors to suppress high-frequency noise from industrial machinery, motors, and variable frequency drives (VFDs) that often share the same power grid as the control system. This prevents electrical noise from disrupting control signals and system performance.

2. Transient Voltage Suppression:

• Equipped with Metal Oxide Varistors (MOVs), this module protects downstream components from voltage spikes caused by external sources like lightning strikes or switching transients, ensuring the protection of costly power supply units (e.g., 51304362-100 or 51304362-150).

3. Industrial-Grade Durability:

• Built for continuous operation in harsh environments, the 51202306-005 is designed to withstand high temperatures, vibrations, and the demanding conditions found in industries like oil refineries, chemical plants, and pulp and paper mills.

4. Passive Component Reliability:

• As a passive filtration device, it boasts an extremely high Mean Time Between Failures (MTBF). In case of a catastrophic power surge, the filter sacrifices itself (via internal fusing or MOV failure), thereby protecting more critical and expensive system components like controllers.

5. System Integration:

• This module is specifically engineered to work seamlessly within Honeywell’s system architecture, filtering incoming 120 VAC or 240 VAC power. Once filtered, the clean power is delivered to the power supply modules (e.g., 51309288-225), which then convert it to DC power for the controller backplane.

Technical Specifications:

Installation Considerations:

• Mounting Surface: Ensure that the surface is flat and smooth (milled or spot-faced) to optimize the power flow and achieve the best noise suppression performance.

• Torque Specifications: When installing the module, it is recommended to torque the mounting hardware to 4.5 N·m (40 in-lb).

• Cabling: Use shielded cables for connecting the filter module to the power entry panel to minimize electromagnetic interference (EMI) during operation.

Technical Note: The 51202306-005 requires proper integration with Honeywell’s Power Supply Units and controllers. Ensure the system is configured to deliver appropriate filtered power to the I/O modules for optimal performance.
