Invensys, a multinational corporation, operated from 1999 to 2014, specializing in industrial automation technology. They offered a wide range of products and services, including Distributed Control Systems (DCS), Safety Instrumented Systems (SIS), and automation software.
Subsidiaries:
TRICONEX: TRICONEX focused on safety-critical systems, particularly:
- Safety Instrumented Systems (SIS): Computer-based systems designed to protect personnel, equipment, and the environment in plants by taking automatic actions when process deviations from safe operating conditions occur.
- Safety Controllers and I/O Modules: TRICONEX provided dedicated hardware components for building reliable and high-integrity SIS solutions.
FOXBORO: FOXBORO, established in 1908, is a renowned brand in the industrial automation industry, known for:
- Distributed Control Systems (DCS): Large-scale computer systems used to monitor and control complex industrial processes across various departments.
- Measurement and Instrumentation: FOXBORO offered a variety of sensors, transmitters, and other instruments for measuring various process variables such as pressure, temperature, and flow.
In 1983, Invensys acquired TRICONEX, making it a subsidiary of Invensys. In 1999, Invensys acquired FOXBORO, making it another subsidiary of Invensys. Under Invensys' leadership, TRICONEX and FOXBORO operated as independent business units, complementing each other's products. FOXBORO's DCS provided overall process control, while TRICONEX's SIS ensured safety by acting as a separate layer in critical situations. Invensys may have offered integrated solutions, combining FOXBORO's DCS with TRICONEX's SIS for comprehensive process control and safety in industrial plants.
In 2014, Schneider Electric acquired Invensys. Today, Schneider Electric provides a unified portfolio of industrial automation products, integrating the technologies of Invensys and its legacy products. Schneider Electric continues to use the TRICONEX and FOXBORO brands for specific product lines related to safety systems and process control.
