Applied Energy Systems Introduces New SEMI-GAS® GigaGuard GSM-V™ Controller to Replace Legacy GSM-5™ Gas Safety Monitor

The GSM-V™ Offers Updated Touchscreen Interface and Added Features in a Simple, Plug and Play Upgrade

MALVERN, PA, JUNE 30, 2017 — Applied Energy Systems (AES), provider of high and ultra high purity gas systems, services, and solutions – including design, manufacturing, testing, installation, and expert field service – has introduced the GigaGuard™ GSM-V™ Controller to replace the GSM-5™ Gas Safety Monitor, a legacy technology from the company’s SEMI-GAS® line of ultra high purity gas delivery systems. The new controller has been modernized with a color touchscreen interface as well as an EtherCAT PLC-based control system, and is optimized for hassle-free, drop-in replacement by customers to easily upgrade AT-Plus Series gas source systems that currently use the GSM-5™. For legacy switchover systems, (2) GSM-V™ controllers replace (2) GSM-5 controllers, (1) AS200 controller, and (1) MPC controller.

The GSM-V™, which conforms to SEMI S2 standards, is identical to its predecessor in form factor, shape, dimension (8” T x 10” W x 12” D), and mounting and connector locations, but now includes added features to improve ease of use and monitoring flexibility. Key upgrades to this programmable controller include:

  • A 7” Beckoff color touchscreen interface that offers step by step guides for purging, cylinder changeout, daily operations, data logging, and input and output configurations to minimize human error.
  • Control for (8) solenoid valves, with the option for expansion to control up to (14) solenoid valves.
  • Monitors digital and analog process sensor inputs and (8) configurable Form C relay outputs.
  • Ethernet-ready communications and capability to integrate with a facility’s safety monitoring system.

“Our customers have been asking for a modern alternative to the microprocessor-based GSM-5 controller, and our controls engineering team has delivered it with the GSM-V,” said Dave Stetz, Chief Engineer of R&D Controls Technology at Applied Energy Systems. “The addition of a touchscreen, PLC-based control system, and expansion options make it simpler to program, operate, and configure for each customer’s unique environment. Not only is the GSM-V superior to the GSM-5 in its gas safety monitoring capabilities, but it takes customers just minutes to make the replacement. It is designed to ‘plug and play’ so that with a few steps, they can immediately start experiencing the benefits of these new features.”

Customers interested in upgrading to the GSM-V™ controller can contact AES at for ordering details.
