SEMI-GAS Systems, a division of Applied Energy Systems Inc of Malvern, PA, USA and a manufacturer of high-purity gas source and distribution systems, has expanded the capabilities of its GigaGuard GSM controller to include PLC operation of 6-, 7- and 8-stick gas distribution systems, providing fully automatic purging capability and gas management from a single source to multiple points of use, as needed in semiconductor and LED manufacturing.
Used in conjunction with the SEMI-GAS Nanoturion valve manifold box, the GigaGuard GSM controller is designed for the safe and continuous distribution of hazardous process gases. It supersedes the previous model with modern PLC technology and enhances the GigaGuard GSM line of semi-automatic and fully automatic distribution controllers.
The adaptable new controller offers adjustable alarm set points and user-configurable inputs and outputs to maximize customization for each application. It also features a 4.3" color touch-screen with software prompts and alarms, helping to reduce operator error and increase safety, the firm adds.
The GigaGuard independently operates ESO valves, monitors analog and digital process sensors, displays delivery pressures, maintains alarm logs, and continuously monitors system operations for hazardous conditions. For added safety, both local and remote system shutdown capabilities are incorporated in the event of an alarm trip.
All GigaGuard controllers meet SEMI S2, SEMI S8 and uniform fire code requirements, as required for the safe handling of hazardous process gases. The controller enclosure is constructed of 16-gauge steel and includes a SEMI-approved EMO (emergency off) button and multi-color LED panel status lights. A flip-down door provides access to controller components, including the Siemens S7-1200 series PLC.
"The new GigaGuard controller offers a dramatic upgrade in performance, versatility and value compared to the previous version," says SEMI-GAS Systems' division manager Jim Murphy.
