Industrial Hazardous Area Applications

Offshore Oil & Gas Production: Monitor wellhead pressures, separator levels, and pipeline flow rates in Zone 1 classified areas on offshore platforms. The intrinsically safe design eliminates ignition sources, enabling direct installation of I/O modules in process areas without expensive purged enclosures. HART communication provides real-time diagnostics for predictive maintenance on remote platforms where equipment access is limited by weather and logistics.

Refinery Process Units: Acquire signals from transmitters in crude distillation, catalytic cracking, and alkylation units where flammable hydrocarbon vapors create Zone 1 hazardous areas. The 8-channel module consolidates multiple measurement points in a single card, reducing cabinet space requirements and simplifying wiring in congested marshalling rooms serving large process units.

Chemical Manufacturing: Interface with reactor temperature, pressure, and level transmitters in batch and continuous chemical processes. The intrinsically safe barrier function built into each channel eliminates the need for external Zener barriers or galvanic isolators, reducing installation costs and improving system reliability by eliminating potential failure points in the signal chain.

Pharmaceutical Production: Connect to validated pressure, temperature, and flow transmitters in clean-in-place (CIP) systems, fermentation vessels, and sterile filtration skids located in classified areas. The module's conformal coating provides ISA-S71.04-1985 Class G3 protection against corrosive cleaning agents and sanitizing chemicals used in pharmaceutical manufacturing environments.

LNG Terminals & Storage: Monitor cryogenic temperature, pressure, and level measurements in liquefied natural gas (LNG) import/export terminals and storage facilities. The extended operating temperature range (-40°C to +70°C) accommodates outdoor installations in arctic and desert climates without environmental enclosures or temperature control systems.

Advanced HART Communication Features

Unlock the full potential of smart field instrumentation in hazardous areas:

• HART v7 Pass-Through: Access primary variable, secondary variables, device status, and diagnostic information through AMS Device Manager
• Multi-Variable Support: Simultaneously acquire temperature, pressure, and calculated values from multi-variable transmitters without consuming additional I/O channels
• Remote Diagnostics: Monitor transmitter health, calibration drift, process alerts, and sensor degradation from the control room
• Remote Configuration: Adjust transmitter parameters, perform zero/span calibration, and configure damping without entering hazardous areas
• Fast Update Rates: HART data refreshes faster than 1 second depending on communication loading and device type

Intrinsically Safe Design Advantages

Critical benefits for hazardous area installations:

• Integrated IS Barriers: Built-in intrinsic safety barriers eliminate external Zener barrier racks, reducing cabinet space and wiring complexity
• Zone 0 Certification: Highest level of intrinsic safety protection enables installation in areas with continuous explosive atmosphere presence
• Simplified Installation: Direct connection to field transmitters without intermediate safety barriers or isolators
• Reduced Maintenance: Fewer components in the signal chain means fewer potential failure points and lower maintenance overhead
• Hot-Swap Capability: Replace failed modules without system shutdown in non-hazardous control room environments

Installation & System Integration

Engineered for efficient deployment in DeltaV M-series I/O architectures:

• Mounts on DeltaV I/O carrier with T-type DIN rail installation
• Includes IS terminal block for safe field wiring termination
• Hot-swappable design enables module replacement without system downtime (in non-hazardous areas)
• Conformal coating provides ISA-S71.04-1985 Class G3 protection against airborne contaminants
• IP20 protection rating suitable for control room and marshalling cabinet environments
• No calibration required - factory calibrated for life

Diagnostic & Fault Detection

Comprehensive diagnostics ensure measurement integrity:

• Open Circuit Detection: Automatic detection of broken wires or disconnected transmitters
• Short Circuit Detection: Identifies wiring faults that could compromise intrinsic safety
• Over-Range Detection: Alerts when input signal exceeds 4-20mA range
• Under-Range Detection: Detects signals below normal operating range
• Module Health Monitoring: Continuous self-diagnostics report module status to DeltaV controller
• HART Device Diagnostics: Access transmitter-specific diagnostics through HART protocol
