Allen-Bradley 80190-380-02-R Signal Conditioning Board

Description

The Allen-Bradley 80190-380-02-R is a signal conditioning circuit board assembly designed specifically for industrial inverter and variable frequency drive (VFD) systems. The 80190-380-02-R operates as a critical intermediary interface that processes, scales, and linearizes feedback and control signals from the field before they reach the main controller logix core. By supporting standard industrial analog signal formats and providing galvanic channel isolation, this assembly effectively eliminates ground loops and dampens high-frequency electromagnetic interference (EMI) typical in high-power electronics environments.

Features

• Equipped with 8 isolated input channels to maximize electrical protection and suppress field-side signal noise
• Features 4 isolated output channels for precise routing and allocation of conditioned control loops
• Universal integration flexibility with direct support for standard 0-10V voltage and 4-20mA current loops

Applications

• Inverter control loop signal conditioning and feedback isolation
• Interface adaptation for industrial variable frequency drives (VFDs)
• Multi-channel analog data acquisition in electrical power sub-assemblies

Installation Guidelines

• Power Quality: Connect a stable 24V DC (+/-10%) external power supply. Avoid sudden voltage surges to preserve the measurement linearity and calibration of the operational amplifiers.
• Isolation Wiring: Utilize the independent channels correctly; do not tie the reference grounds of isolated fields together, as it defeats the board's built-in galvanic isolation barrier.
• Environmental Layout: Mount the board inside an appropriately rated enclosure to maintain operations within the specified -20 degC to +60 degC temperature window and prevent condensation.
