The MAC PPC5C-DGB-PGEA-HAE-B0-9 is a precision proportional pressure controller designed for industrial applications requiring reliable pneumatic pressure regulation. Key Specifications Port Size: 1/8" NPTF side ports, ensuring compatibility with standard pneumatic systems. Output Pressure Range: 0–90 PSI, providing precise control within a broad operational span. Max Inlet Pressure: 120 PSI, allowing robust performance under high-pressure conditions. Power Supply: 24 VDC (20.4–26.4 VDC range), with low current consumption (50–275 mA for single transducer models). 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 industrial automation, machinery control, and process systems requiring proportional pressure regulation. Its compact design and high accuracy make it suitable for applications such as robotics, material handling, and pneumatic actuation.
