The MAC PPC5C-AAA-HGAB-CAA-GD is a compact proportional pressure controller designed for precise pneumatic pressure regulation in industrial applications. Key Specifications Output Pressure Range: 0–20 PSI, providing accurate control for low-pressure systems. Max Inlet Pressure: 120 PSI, ensuring reliable operation under specified conditions. Power Supply: 24 VDC (20.4–26.4 VDC range), with low current consumption (50–275 mA for single transducer models). Port Size: 1/8" NPTF side ports, ensuring compatibility with standard pneumatic systems. Flow Capacity: Cv 0.07/70 Nl/min (fill/exhaust), enabling efficient air handling and fast response times. Technical Features Closed-Loop Control: Uses two MAC 34 Series balanced poppet valves for rapid response and minimal overshoot/undershoot. Command Signal: Accepts 4–20 mA analog input, with differential configuration for noise immunity. Monitoring: Includes 0–10 V analog monitor signal (AMS) for pressure verification and TTL logic monitor signal (LMS) for "go/no-go" status feedback. Enclosure: Sealed aluminum housing with IP65 protection, resisting dust and water ingress for reliable operation in harsh environments. Performance Advantages Accuracy: ±1.5% full scale, combining linearity and hysteresis for precise pressure control. Temperature Range: Operates in ambient temperatures from 0–50°C (32–122°F), suitable for diverse industrial conditions. Vibration Resistance: Unaffected by mechanical vibrations, ensuring stable performance in dynamic settings. Mounting Flexibility: Installable in any orientation, offering adaptability to space-constrained systems. Applications Ideal for applications requiring precise low-pressure regulation, such as robotics, automation, and process control systems. Its compact design and high accuracy make it suitable for environments where space is limited and reliable performance is critical.
