Hong Kong Power Plant

All of the electricity for Hong Kong island is produced at the Lamma Power Station. The Lamma Power Station in Hong Kong is using Opto 22 SNAP PAC standalone controllers to control heat, pressurization and other critical processes. The Opto 22 PACs connect to weigh scales, conveyors, pressure transducers, and thermocouples to ensure that the coal burning operations taking place at Lamma are executed safely and optimally.

For example, analog I/O modules wired to scales measure the weight of the coal prior to its delivery to the furnaces and sends these figures to the controller. Based on these readings—and whether they're low or high—the controller then instructs the conveyors delivering the coal to the furnaces to speed up or slow down appropriately, so the furnaces generate the proper amount of heat needed to spin turbines that produce the power.

At the same time, integrated circuit temperature derivative probes (ICTDs) connected to thermocouple analog input modules monitor the actual furnace temperatures, which are then used in PID calculations to regulate the temperature via analog output modules.

For this project Worldwide Exporters exported all of the Opto 22 equipment. Worlwide Exporters also has the ability to export many related goods such as mounting cabinets, networking equipment, conduit, panduit, mounting hardware, instrumentation, alarm panels and HMI touchscreens.


Metro Madrid

The Opto 22 SNAP PAC Ethernet I/O system is used to monitor Madrid Metro's entire communications network including the radio links used for voice and data transmission throughout the stations, two-way communication between the trains and the station, and driver communication with maintenance personnel. Also installed throughout these stations is a system of public intercom phones that allow passengers to communicate with the station manager.

The Opto 22 SNAP PAC Ethernet I/O system transmits critical operational data from the connected devices and systems through the Madrid Metro's Ethernet network to management consoles in the Metro Control Center.
