What Is SCADA? Supervisory Control Without Replacing the PLC
SCADA sits above PLCs and RTUs: it acquires field data, alarms operators, and issues supervisory commands across plants and remote assets—without replacing local deterministic control.

Designed for robust speed control in industrial three-phase systems, the FR-E840-0170-4-60 variable frequency drive operates within the high-performance Mitsubishi Electric FR-E800 family. This compact, versatile inverter supports 400V class three-phase electrical supplies, delivering efficient control of induction and permanent magnet motors. Featuring an integrated conformal circuit board coating (denoted by the -60 suffix), the unit is optimized for protection against harsh atmospheric conditions such as humidity, dust, and corrosive vapors, ensuring long-term operational reliability in demanding production environments.
The unit features analog voltage monitoring via the dedicated AM terminal and is configured with source logic for both standard input signals and its integrated safety stop loop. It is engineered to seamlessly integrate into standardized control architectures, offering a balanced power-to-size ratio suited for decentralized control cabinets and modular machinery designs.
