PC320 Process Controller

The PC320 Process Controller: A Versatile Tool for Precise Measurement and Control
The PC320 process controller is a robust and user-friendly device designed for monitoring and regulating various industrial processes. Here’s a detailed breakdown of its key features:

Intuitive User Interface and Flexible Sensor Compatibility

Digital LCD Screen: Provides clear and concise information about the sensor being monitored, including the current reading, selected engineering units, and the status of each relay. Backlighting ensures easy viewing even in low-light conditions. Power-saving mode helps conserve battery life in portable applications.
User-Selectable Sensor Types: The PC320 comes pre-programmed for 12 common sensor types, eliminating complex configuration for standard applications. Additionally, it allows for custom sensor integration with user-defined engineering units, offering exceptional versatility.

Advanced Calibration and Data Processing

2 and 3-Point Calibration Methods: Supports both basic and advanced calibration techniques for improved sensor accuracy.
3rd Order Polynomial Equation: This feature allows for correcting non-linearities in sensor output, ensuring highly reliable data even for sensors with complex response curves.
Programmable Averaging: Users can define the averaging period for sensor readings, effectively filtering out short-term fluctuations and providing a more stable representation of the process variable.

Comprehensive Monitoring and Control Capabilities

4-20mA Analog Output: Transmits sensor data to external devices like data loggers, PLCs, telemetry systems, and chart recorders for recording and analysis.
Four Programmable Relay Outputs: Offer a high degree of control over external equipment based on sensor readings. Each relay can be independently programmed for various triggering conditions.

Five Control Modes:
One Time Trigger: Activates a relay for a set duration when a sensor reading deviates from the normal range.
Steady State Mode: Maintains relay activation as long as the sensor reading remains outside the normal range.
Cyclic Mode: Repetitive on-off cycles for the relay based on user-defined durations, continuing as long as the sensor reading is abnormal.
High Control and Low Control Modes: Focus on maintaining the sensor reading within a specific range, ideal for applications like controlling tank liquid levels.
Relay Deactivation Mode: Allows manual override to deactivate a relay regardless of programmed settings.
Additional Features for Enhanced Performance
Delay Times: Prevent relays from reacting impulsively to minor sensor fluctuations near threshold levels by introducing a programmed delay before activation.
Hysteresis: Ensures relays remain engaged even when sensor readings briefly return to the normal range, preventing excessive cycling due to rapid changes near the threshold.
Relay Test Mode: Facilitates manual verification of relay functionality.

In Conclusion

The PC320 process controller is a powerful tool that caters to a wide range of industrial applications. Its user-friendly interface, extensive sensor compatibility, advanced calibration options, and versatile control features make it ideal for tasks requiring precise measurement and control of various process variables. Whether you need to monitor temperature, pressure, flow rate, or any other sensor-detectable parameter, the PC320 offers the accuracy, flexibility, and control capabilities to ensure your process runs smoothly and efficiently.
