Features:
- Dedicated industrial-grade voltage feedback board
- Manufactured by Allen-Bradley/Rockwell Automation
- Designed for deployment in heavy-duty onboard socket interfaces in medium voltage (MV) SMC-Flex solid-state smart motor controllers
In practical industrial drive and power grid monitoring applications, this feedback board primarily provides multi-channel voltage sampling, isolation conversion, and system operation status protection functions. It can simultaneously monitor the real-time voltage status at the three-phase AC power input, both ends of the DC bus, and the inverter output.
When transient voltage surges, harmonic filtering distortion, or sudden drops in grid voltage occur on the industrial bus, this control board can capture abnormal signals with an extremely high sampling rate and provide the feedback signals required for closed-loop regulation to the upper-level control board. It is an indispensable basic hardware guarantee for industrial systems to achieve precise speed control, dynamic overvoltage/undervoltage protection, and fault-tolerant interlocking.
The 81000-199-52-R Allen Bradley Feedback board may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The 81000-199-52-R feedback board operates using its onboard precision resistor divider network and high-speed opto-isolation circuitry (electrical isolation). Medium-voltage AC or DC signals from the field are first connected to 26 screw terminals. After onboard step-down and signal conditioning circuitry, the high-voltage signal is proportionally converted to a low-voltage analog signal. To prevent damage to the control center from strong electromagnetic interference and high-voltage backlash, the low-voltage analog signal is completely physically and electrically isolated via high-isolation opto- or magneto-electric coupling elements.
- SMC-Flex Motor Controller: Operates as a critical safety feedback element within medium-voltage solid-state starters (typically in 2.4kV to 6.6kV systems).
- Real-time Phase Diagnostics: Provides the controller with phase calibration, raw voltage fluctuations, and voltage imbalance indicators to trigger protective trip circuits immediately before thermal damage occurs in the motor's high-capacity windings.
- SCR Trigger Synchronization: Provides precise sinusoidal crossover input, crucial for coordinating accurate SCR pulse trigger sequences during controlled soft-start or deceleration cycles.
