Features:
- INTERFACE BOARD FOR POWERFLEX 7000
- Voltage Feedback Interface Board designed for medium-voltage industrial control systems
- Primarily used to provide accurate voltage monitoring and feedback to programmable logic controllers (PLCs) or motor drives
Its core function is to monitor key voltage parameters within the frequency converter in real time and convert high-voltage signals into low-voltage feedback signals recognizable by the control system. This module provides high-precision voltage data, ensuring voltage stability and output accuracy of the motor drive system during startup, operation, and speed regulation, making it a crucial component for maintaining the efficient operation of high-power industrial equipment.
Furthermore, this interface board plays a vital role in system safety protection and diagnostics. It features excellent electrical isolation performance, effectively blocking interference from the high-voltage side to the low-voltage control circuitry and preventing damage to the core controller from inrush currents or fault currents.
The 81000-199-53-R Allen Bradley INTERFACE BOARD may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Simultaneously, it supports multiple industrial communication protocols (such as ControlNet or DeviceNet), enabling the PLC to remotely monitor voltage status. Upon detecting abnormal voltage, the system can quickly trigger alarms or shutdown protection, thereby extending equipment life and reducing maintenance costs. Its operating principle is based on signal attenuation and optical isolation technology: the module captures high-voltage AC or DC signals from the main circuit through a high-impedance input terminal and attenuates them proportionally to a safe range using a precision voltage divider circuit.
Heavy industrial infrastructure: You'll find these circuit boards in industries requiring high-torque, high-voltage machinery, such as:
Oil and gas: Controlling large pumps and compressors.
Mining: Powering conveyors, crushers, and grinders.
Water treatment: Managing large-capacity water pumps.
Marine: Regulating propulsion systems and thrusters.
