In the mid-90s, Indian industries and OEMs faced a critical gap — no indigenous manufacturer offered reliable self-tune PID controllers. The market was largely dominated by high-cost European and American brands or lower-cost imports that often fell short of industrial-grade performance.

Rising to the challenge, PPI undertook a focused development effort spanning over three years, culminating in the launch of the “Neuro Series” – Universal Self-Tune Process Controllers. These innovative controllers set a new benchmark in control accuracy, responsiveness, and long-term reliability. With this achievement, PPI earned the distinction of introducing India’s first fully indigenously developed self-tune PID controllers, empowering domestic industries with world-class automation technology.

At PPI, innovation begins with a clear understanding of process dynamics and equipment functionality. This expertise has led to the development of Application-Specific Integrated Controllers – intelligent systems engineered to meet the precise requirements of specialized equipment.

PPI’s solutions include the HimiTherm series for Stability and Environmental Test Chambers, the Clavex series for Hospital and Laboratory Autoclaves, the LabCon series for Laboratory Ovens, Furnaces, and BOD Chambers, and the Frizcon series for Deep Freezers and Ultra-low Cooling Cabinets. Select variants of these controllers also feature built-in data logging, supported by free 21 CFR Part 11 compliant PC software – helping customers meet regulatory and audit requirements with ease.

Designed for seamless integration, long-term reliability, and optimal process control, these application-specific systems have become the go-to choice for OEMs seeking performance, compliance, and customization in one powerful package.

In regulated industries like Pharmaceuticals and Chemicals, ensuring data integrity and compliance is critical. Traditional logging methods such as chart recorders and PC-dependent systems often posed challenges related to reliability, maintenance, and data security.

PPI addressed these gaps by engineering a versatile range of standalone Data Logging Systems with built-in memory – eliminating the need for continuous PC connectivity. Variants include USB (pen-drive) interface models for offline transfer, PC interface models for data download, as well as expandable and composite versions to suit varying application needs.

Taking a leap forward, PPI also introduced Web-based Central Monitoring Systems, enabling real-time data acquisition, visualization, and archival over standard browsers without the need for dedicated software.

With these innovations, PPI has redefined data logging for the modern factory – creating a compliant, connected, and scalable ecosystem for process monitoring and control.

As industries embraced distributed control and connectivity, PPI led the way by developing MODBUS-based Digital and Analog I/O Modules – enabling smarter, scalable automation across sectors.

Available in Serial (RS-485) and Ethernet (TCP/IP) variants, these modules replaced conventional wiring with protocol-driven architectures, allowing real-time signal acquisition and control from both remote and centralized setups.

With support for digital and analog I/O, relay switching, and signal isolation and conversion, PPI’s rugged, plug-and-play modules integrated seamlessly with SCADA, PLC, and DCS platforms via MODBUS RTU/TCP. Advanced features like channel-wise configuration, watchdog timers, and fail-safe states made them ideal for mission-critical applications.

By pioneering this modular approach, PPI helped industries transition to connected, resilient, and future-ready control systems – shaping the foundation for IIoT-driven automation.
