Industrial Process Applications

Pressure Measurement Systems: Interface differential pressure transmitters for flow measurement in pipelines, level monitoring in vessels, and filter differential pressure tracking. The terminal block's 2-wire support enables loop-powered transmitters to draw power directly from the DeltaV system, eliminating the need for separate field power supplies and simplifying installation.

Temperature Monitoring Networks: Connect 4-20mA temperature transmitters with RTD or thermocouple inputs for reactor temperature control, heat exchanger monitoring, and product temperature tracking. The 4-wire configuration accommodates externally powered transmitters requiring higher current draw for advanced diagnostics or multi-variable outputs.

Flow Metering Infrastructure: Integrate electromagnetic, vortex, and Coriolis flowmeters for custody transfer, batch control, and process optimization. The terminal block's key-coded design ensures compatibility with DeltaV analog input cards, preventing wiring errors during installation or maintenance activities.

Level Control Applications: Wire radar, ultrasonic, and guided wave radar level transmitters for tank farm management, separator interface detection, and reactor level control. The robust screw terminal connections withstand vibration and thermal cycling in outdoor installations and non-climate-controlled equipment rooms.

Analytical Instrumentation: Connect pH meters, conductivity analyzers, dissolved oxygen sensors, and turbidity meters in water treatment, pharmaceutical, and food & beverage applications. The terminal block's conformal coating protects against airborne contaminants and corrosive atmospheres common in chemical processing environments.

2-Wire vs 4-Wire Configuration Advantages

2-Wire Loop-Powered Transmitters:

• Simplified wiring with only two conductors required per channel
• Transmitter draws power from the 4-20mA signal loop
• Reduced installation costs and cable tray congestion
• Ideal for standard pressure, temperature, and flow transmitters
• Lower power consumption per channel

4-Wire Externally Powered Transmitters:

• Separate power and signal circuits for maximum noise immunity
• Supports high-power transmitters with advanced features
• Enables HART communication without signal interference
• Accommodates multi-variable transmitters with secondary outputs
• Provides galvanic isolation between power and measurement circuits

Rugged Environmental Performance

Engineered for reliable operation in demanding industrial conditions:

• Extended Temperature Range: -40°C to +70°C operation accommodates outdoor installations, arctic climates, and desert environments without performance degradation
• Shock Resistance: 10g half-sine wave for 11ms withstands mechanical impacts from nearby equipment, seismic events, and transportation
• Vibration Tolerance: 1mm peak-to-peak (2-13.2 Hz), 0.7g (13.2-150 Hz) for installations near compressors, pumps, and rotating machinery
• Humidity Resistance: 5% to 95% non-condensing operation in coastal, tropical, and high-humidity environments
• Conformal Coating: ISA-S71.04-1985 Class G3 protection against airborne contaminants, corrosive gases, and industrial pollutants

Installation & System Integration

Designed for efficient deployment in DeltaV I/O architectures:

• DIN Rail Mounting: T-type DIN rail installation on DeltaV I/O carriers for flexible cabinet layouts and easy module replacement
• Key-Coded Design: Mechanical keying ensures terminal block compatibility with corresponding analog input cards, preventing installation errors
• Screw Terminal Connections: Secure, vibration-resistant wire terminations accept 22-14 AWG (0.32-2.5mm²) field wiring
• No Calibration Required: Factory configured and tested - no field calibration or user-serviceable adjustments needed
• Compact Footprint: Space-efficient design maximizes channel density in marshalling cabinets and control rooms

Field Wiring Best Practices

Maintenance & Lifecycle Management

Designed for long-term reliability with minimal maintenance requirements:

• No User-Serviceable Parts: Sealed construction eliminates the need for periodic maintenance or calibration
• Hot-Swap Capability: Terminal blocks can be replaced without powering down the entire I/O system (follow proper procedures)
• Visual Inspection: Periodic checks for loose connections, wire damage, or corrosion recommended annually
• Spare Parts Strategy: Maintain spare terminal blocks for critical applications to minimize downtime during failures
