ABB AWT200062 Insulation Resistance Module

Description

ABB AWT200062 Insulation Resistance Module

The ABB AWT200062 is an internal, hardware-level electronic module that serves as the main component for the ABB AWT210 Series 2-Wire Universal Transmitter. The AWT210 system is highly regarded in continuous water analysis for measuring critical liquid parameters like pH, ORP (Oxidation-Reduction Potential), and conductivity.

Because AWT200062 is the specific assembly part number for the core control unit (often handling signal conditioning, processor functions, and power distribution), its parameters and characteristics are aligned directly with the AWT210 operational framework.

Product Detailed Description

The AWT200062 acts as the core controller and internal “engine” of the AWT210 transmitter. It is a 2-wire device designed for plug-and-play modularity. The module handles high-precision conversion of low-level analog signals coming from analytical chemistry sensors, filters out industrial noise, and converts the readings into a standardized network protocol or loop current (4–20 mA).

Technical Parameters

Product Advantages

• True Modular Plug-and-Play: The AWT200062 control board architecture allows users to easily swap or upgrade sensor modules and communication cartridges in the field without needing to replace the entire transmitter housing.
• Intrinsically Safe Design: Engineered to satisfy strict Ex ia explosion-proof requirements, allowing safe deployment in hazardous chemical and gas environments when powered via a safety barrier.
• One-Button Calibration: Works alongside ABB’s intuitive local software interface to enable simple, fast on-site calibration, slashing routine maintenance times.
• Rugged Signal Integrity: Incorporates high galvanic isolation and advanced filtering to guarantee precise readings even when positioned near large motors or noisy variable frequency drives (VFDs).

Important Considerations & Precautions

• Discontinued Status Note: As an individual spare component assembly, the AWT200062 part number is heavily associated with legacy or factory-level part replacement channels. Ensure compatibility with your existing AWT210 outer housing revision before ordering swap-outs.
• Power Restrictions: If you are operating in a hazardous area, strict compliance with the maximum 30 V DC input threshold is critical. Exceeding this limit will breach the intrinsic safety certification.
• Moisture Preservation: While the final AWT210 enclosure is rated to IP66/NEMA 4X, the inner AWT200062 module is bare electronics. Keep the outer enclosure door securely latched and clean during field wiring to avoid moisture ingress on the board.
• Sensor Co-configuration: When replacing this board, remember to re-configure the device jumpers or digital software settings to precisely match the target sensor technology (e.g., matching a glass pH electrode vs. a toroidal conductivity sensor).

Product Applications

The AWT200062/AWT210 combination is standard equipment across industries relying on continuous water monitoring:

• Water & Wastewater Treatment: Continuous measurement of pH levels during neutralization or tracking conductivity in effluent streams.
• Chemical Processing: Monitoring toxic or highly corrosive chemical solutions where intrinsically safe instruments are mandated.
• Pulp & Paper Production: Managing raw stock, refiners, and headbox chemical balances to preserve optimal pulp quality.
• Power Generation: Monitoring boiler feedwater and condensate purity to prevent scale build-up and structural pipe corrosion.
