Description

The Foxboro A201SR04 is part of the Foxboro I/A Series of process control systems.

Product Name:

Foxboro A201SR04 – I/A Series Universal Input Module

Product Description:

The Foxboro A201SR04 is a modular input card that supports a range of input types for measurement and control in process automation systems. The module is designed for use in the Foxboro I/A Series systems and offers a wide variety of input configurations, such as thermocouples, RTDs, voltage, current, and resistance. It is typically used in distributed control systems (DCS) to interface with field sensors, providing accurate measurement and control in real-time process applications.

Product Parameters & Specifications:

• Input Types Supported:
  • Thermocouples (Type J, K, T, E, etc.)
  • RTDs (PT100, PT1000)
  • Voltage Inputs (0-10 V, 1-5 V)
  • Current Inputs (4-20 mA, 0-20 mA)
  • Resistance Inputs (e.g., for level sensors)
• Input Range:
  • Wide input ranges for different types of thermocouples, RTDs, and analog signals.
• Signal Conditioning:
  • Built-in signal conditioning to convert raw sensor signals into digital values that can be processed by the control system.
• Accuracy:
  • Typically, modules like the A201SR04 have high accuracy (±0.1% or better, depending on the specific input type).
• Power Supply:
  • The module typically operates with a 24V DC power supply.
• Communication Protocol:
  • Compatible with the Foxboro I/A Series communication protocols, which support real-time data exchange over a control network (e.g., Profibus, Modbus, etc.).
• Digital Conversion:
  • Typically uses high-precision ADCs (Analog-to-Digital Converters) for converting analog signals into digital data.
• Dimensions:
  • The module usually fits within the standard size constraints for I/A Series racks or chassis, often around 3-4 inches wide (for 1-2 slot modules).
• Operating Environment:
  • Temperature range: -10°C to 60°C (14°F to 140°F)
  • Humidity: 5% to 95% relative humidity, non-condensing
  • Shock and vibration resistance suitable for industrial environments.
• Mounting:
  • The module is designed to be mounted in standard Foxboro I/A Series chassis or racks, typically as part of a larger distributed control system (DCS) network.
• Input Isolation:
  • The module provides galvanic isolation for the inputs, reducing the effects of noise and interference on measurement signals.
• Fault Tolerance:
  • Built-in diagnostics and error checking to detect and report issues with input signals or module operation.

Product Use:

The Foxboro A201SR04 Universal Input Module is used for:

1. Industrial Process Control:
   • It serves as an interface between field instruments (like temperature sensors, pressure transducers, or flow meters) and the control system. By converting analog signals into digital data, it allows for real-time monitoring and control of various process parameters.
2. Monitoring and Data Acquisition:
   • Collecting data from various types of sensors and feeding it into the control system for further analysis, alarm generation, or automatic control.
3. Energy Management:
   • Often used in industries such as power generation, where precise measurement of temperature, pressure, or flow is critical for energy optimization and system safety.
4. Automation Systems:
   • Integrated into DCS or PLC systems to enable efficient and reliable control in manufacturing, refining, and chemical processes.
5. Process Optimization:
   • Provides accurate, reliable inputs that help optimize operations, improve process stability, and reduce downtime through timely diagnostics and alerts.
6. Environmental Monitoring:
   • Used in applications like water treatment plants or emissions monitoring systems to gather critical data about temperature, pH, and other environmental variables.
