Description
The ORCA-101 Electronic Control Unit (ECU) is the central command, computing, and optical measurement engine of the OndaVia Raman Controller Automation (ORCA) on-line process analytical system. Engineered for rugged industrial plant environments, the ORCA-101 houses an embedded industrial Windows PC, a solid-state Quantitative Raman Spectrometer (QRS), an integrated optical flow cell interface, and extensive plant communications telemetry (Modbus TCP/IP, RS-485, and 4–20 mA current loops) to orchestrate continuous, automated chemical speciation and real-time DCS control.
- Centralized Process Orchestration: Sequences automated sampling cycles, microfluidic reagent introduction, and optical readouts across connected fluidic units.
- Multiplexed Channel Scalability: Can be interfaced simultaneously with multiple fluidic modules (such as ORCA-201 Amines or ORCA-202 Ammonia) to analyze diverse chemical targets from a single hub.
- High-Resolution QRS Engine: Solid-state Raman spectrometer measures precise molecular vibrational fingerprints with zero moving optical components.
- Integrated Optical Flow Cell: Precision flow interface for automated transmission analysis of conditioned slipstream samples.
- Automated Limit & Frequency Tuning: Software settings allow operators to configure testing intervals (1 to 12 tests/hr) and optimize target detection ranges.
- Industrial Windows PC: Ruggedized embedded computing core designed for continuous 24/7/365 process control service.
- Telemetry Hub: Isolated 4–20 mA analog outputs, Modbus TCP/IP over Ethernet, and RS-485 serial communications.
- Local Display (Optional): Integrated industrial touchscreen for on-unit real-time data visualization and manual diagnostic control.
- Dual Power Supply Options: Field-configurable for 120/240 VAC (50/60 Hz) or 24 VDC industrial plant power.
- Enclosure & Purge Compatibility: NEMA 4X / IP66 rated, with purge-and-pressurization readiness for Class I, Division 2 hazardous locations.
