• Product Type: 8-channel Analog Input Module (for DeltaV DCS)
• System Compatibility:
  • Works with DeltaV v13.3+ software and DeltaV I/O racks (e.g., Electronic Marshalling Chassis, Standard I/O Chassis).
  • Supports integration with DeltaV controllers (M-series, S-series) and other system components (e.g., HART communicators).
• Core Function:
  • Converts 4–20 mA analog signals from field instruments into digital data for the DCS.
  • Enables bidirectional communication with HART-enabled devices to retrieve diagnostics, configuration parameters, and secondary variables (e.g., temperature alongside pressure readings).

Technical Specifications

1. Input Configuration

• Channel Count: 8 isolated channels.
• Signal Type: 4–20 mA (loop-powered or externally powered) with HART Protocol v5 or later .
• Input Impedance: ≤ 250 Ω (for HART communication compatibility).
• Accuracy: ±0.075% of full scale (at 25°C) – ensures precise measurements in critical processes.
• Resolution: 16-bit (0.015% of span).
• Response Time: <200 ms (from signal change to DCS update) – suitable for dynamic applications.
• Isolation: 1 kVrms between channels and backplane (per IEC 61010-1) – minimizes noise interference and ground loops.

2. Power Supply

• Backplane Power: 12 V DC (supplied by DeltaV I/O rack), typical current draw: 100 mA.
• Field Power: 24 V DC (for loop-powered transmitters), typical current draw: 56 mA per channel (full load).
• Protection: Reverse polarity and overcurrent protection (self-resetting fuse) – safeguards against wiring errors.

3. Physical & Environmental Specifications

• Dimensions: 125 mm (W) × 75 mm (H) × 25 mm (D) [4.9” × 2.95” × 0.98”] – compact design for space-constrained cabinets.
• Mounting: 19-inch rack-mounted (installs directly into DeltaV I/O chassis).
• Operating Temperature: -40°C to +70°C (-40°F to 158°F) – withstands extreme industrial conditions (e.g., outdoor installations, high-temperature plants).
• Storage Temperature: -40°C to +85°C (-40°F to 185°F).
• Humidity: 5%–95% RH (non-condensing) – suitable for humid environments (e.g., offshore platforms).
• Vibration Resistance: 1 mm peak-to-peak (2–13.2 Hz) or 0.7 g (13.2–150 Hz) per IEC 60068-2-6 – durable against machinery vibrations.
• Shock Resistance: 10 g (11 ms half-sine wave) per IEC 60068-2-27.
• Protection Class: IP20 (front panel) – dust-protected for enclosed control rooms.

4. Safety & Compliance

• Certifications:
  • CE (EN 61326-1 for EMC, EN 61010-1 for safety).
  • UL 508 (industrial control equipment) – compliant for North American markets.
  • CSA C22.2 No. 14 (Canadian safety standard).
  • ATEX/IECEx (via associated barriers or intrinsic safety modules for hazardous areas) .

Key Features

1. HART Communication:
   • Supports HART Protocol v5 or later, enabling remote device configuration (e.g., zero/span adjustment) and diagnostics (e.g., sensor drift alerts) .
   • Allows simultaneous transmission of analog signals and digital data over the same 2-wire loop.
2. Advanced Diagnostics:
   • Built-in Self-Test (BIST): Automatically checks module hardware (power, ADC, HART modem) on startup.
   • Line Fault Detection (LFD): Monitors for open/short circuits, loop current deviations, and HART communication errors; triggers alarms for proactive maintenance.
   • Status LEDs: Dedicated indicators for power (green), communication (yellow), and channel faults (red) – aids in quick visual troubleshooting.
3. Flexible Configuration:
   • Configured via DeltaV Explorer software – supports channel-by-channel setup (e.g., signal range, damping time, HART polling interval).
   • Hot-Swappable Design: Replaceable without shutting down the DCS, minimizing downtime for 24/7 operations.
4. Rugged Construction:
   • Triple conformal coating on circuit boards – protects against moisture, dust, and corrosive gases.
   • Wide temperature range and vibration resistance – ensures reliability in harsh industrial settings.

Applications

• Oil & Gas: Monitors wellhead pressure/temperature transmitters (4–20 mA) and retrieves HART data for predictive maintenance.
• Chemicals & Petrochemicals: Measures flow rates from Coriolis meters and tracks analyzer outputs with HART diagnostics.
• Power Generation: Captures steam turbine vibration sensor signals and manages boiler feedwater control loops.
• Pharmaceuticals: Ensures precise temperature/pressure control in reactors while complying with GMP standards via HART data logging.
• Water & Wastewater: Monitors dissolved oxygen levels in treatment tanks and controls chemical dosing pumps based on HART sensor feedback.
