Process Control I/O Solution – Westinghouse 3A99158G01 (4PCRL1) | Ovation DCS SUB 8 Local I/O Interface Board
Where This Product Is Used
The Westinghouse 3A99158G01 (4PCRL1) SUB 8 Local I/O Interface Board is a critical communication and signal-routing component within the Westinghouse Ovation Distributed Control System (DCS). It is deployed across demanding industrial environments where reliable, high-density local I/O connectivity is non-negotiable:
- Power Generation Plants – Coal, gas turbine, nuclear, and combined-cycle facilities using Ovation DCS for turbine control, boiler management, and balance-of-plant automation.
- Oil & Gas Processing – Upstream and midstream facilities requiring deterministic I/O scanning for safety-critical process loops.
- Chemical & Petrochemical Plants – Continuous process control applications where I/O integrity directly impacts product quality and safety.
- Water & Wastewater Treatment – Municipal and industrial water systems leveraging Ovation for SCADA-integrated process automation.
- Pulp & Paper Mills – High-availability production lines requiring robust local I/O expansion within existing Ovation cabinets.
