Oil & Gas SCADA Applications

Wellhead Monitoring: Acquire discrete signals from wellhead safety shutdown valves, high/low pressure switches, and emergency shutdown (ESD) system contacts. The 16-channel capacity accommodates multiple wells from a single RTU, reducing hardware costs and simplifying remote site installations. The wide input voltage range (10.7-30 VDC) tolerates voltage drops in long cable runs common in oilfield applications.

Pipeline Leak Detection: Monitor pipeline leak detection sensors, valve position limit switches, and pump station alarm contacts along crude oil, natural gas, and refined product pipelines. The non-isolated common ground configuration simplifies wiring when all field devices share the same ground reference, typical in pipeline SCADA systems where RTUs are located in remote pump stations or valve sites.

Tank Farm Automation: Interface with tank level switches (high/high-high, low/low-low), overfill protection systems, and vapor recovery unit status contacts in crude oil storage terminals and refined product distribution facilities. The module's conformal coating (ISA-S71.04-1985 Class G3) protects electronics from corrosive atmospheres common in tank farm environments containing H2S, hydrocarbons, and other airborne contaminants.

Compressor Station Control: Acquire signals from compressor vibration switches, bearing temperature alarms, lube oil pressure switches, and emergency shutdown contacts in natural gas transmission compressor stations. The -40°C to +70°C operating temperature range accommodates outdoor installations in arctic and desert climates without requiring environmental enclosures or heating/cooling systems.

Water & Wastewater SCADA Applications

Lift Station Monitoring: Monitor pump run status, high water level alarms, pump failure contacts, and intrusion detection switches in remote wastewater lift stations. The low power consumption (1.2W typical) enables solar-powered RTU installations where AC power is unavailable, critical for distributed lift station networks in rural areas.

Water Treatment Plant Automation: Interface with filter backwash status contacts, chemical feed pump run confirmation, clarifier level switches, and process alarm contacts in municipal water treatment facilities. The module communicates with ControlWave CPUs via the system bus, supporting Modbus RTU, DNP3, and BSAP protocols for integration with existing SCADA master stations.

Reservoir & Tank Level Monitoring: Acquire signals from float switches, ultrasonic level sensor alarm outputs, and overflow protection contacts in water storage reservoirs and elevated tanks. The 5mA typical input current per channel minimizes power consumption from battery-backed field devices, extending battery life in remote monitoring applications.

Non-Isolated Architecture Advantages

Benefits of common ground configuration for specific applications:

• Simplified Wiring: All field devices share common negative terminal, reducing wire count and terminal block requirements
• Lower Cost: Non-isolated design reduces module cost compared to isolated input modules for budget-conscious applications
• Common Ground Systems: Ideal for installations where all field devices share the same ground reference (typical in single-site RTU applications)
• Reduced Power Consumption: 1.2W typical power draw enables solar-powered RTU deployments

ControlWave System Integration

Seamless integration with ControlWave PAC/RTU platforms:

System Bus Communication: The module interfaces with ControlWave CPUs via the high-speed system bus, providing deterministic I/O updates and eliminating the need for external I/O scanning protocols. Digital input states are mapped directly into the CPU's memory space for immediate access by control logic and communication protocols.

Protocol Support: ControlWave systems support Modbus RTU/TCP, DNP3 (Level 2), BSAP, and OPC for integration with SCADA master stations from Emerson, Schneider Electric, GE, Siemens, and other vendors. Digital input points are automatically mapped to protocol data objects for seamless SCADA polling and event reporting.

ACCOL III Programming: Configure input debounce times, alarm limits, and logic functions using ControlWave Designer software with the ACCOL III function block library. Pre-built function blocks for digital input conditioning, alarm detection, and event logging accelerate application development and reduce commissioning time.
