Technical Data for PCD-Series Pressure Controllers

Product catalog summary
Overview: The document provides technical specifications for the PCD-Series Pressure Controllers, which operate across a range of 0.07 to 3000 PSI in absolute, gauge, or differential pressure models. It includes details on mechanical, sensor, control performance, power, communication, and dimensions.
Mechanical Specifications: The PCD models are compatible with non-corrosive gases, while PCDS models can handle non-corrosive gases, liquids, and some corrosive gases. Sensor burst pressure varies by model, with lower PSI models having a burst pressure of 3x full scale and higher PSI models at 1.5x. The humidity range is 0-95% non-condensing, and ingress protection is rated at IP40.
Sensor and Control Performance: Standard pressure accuracy is ±0.25% of full scale, with high accuracy models at ±0.125%. The steady state control range is from 0.01% to 100% of full scale. Operating temperature ranges from -10 to 60°C, and the sensor response time is less than 1 ms.
Power and Communication: The controllers support various digital input and output options, including RS-232, Modbus, and others. Analog options include 4-20 mA and several voltage ranges. Power requirements vary by model, with PCD and PCDS needing 12-24 Vdc, 250 mA, and PCRD models requiring 24 Vdc, 1 A.
Standard Available Ranges: The document lists available pressure ranges for different models, indicating compatibility with absolute, gauge, and differential pressure measurements.
Wetted Materials: Details on materials used in control valves and measurement heads are provided, including options for stainless steel, Delrin, and various elastomers, depending on the application.
Dimensions and Mounting: The document includes detailed dimensions for various models and configurations, specifying width, depth, height, and port sizes. It also notes the weight of each configuration.
