AES launches PLC-based GSM-V Controller to replace microprocessor-based GSM-5 Gas Safety Monitor
Applied Energy Systems (AES) of Malvern, PA, USA – which provides high- and ultra-high-purity gas systems, services, and solutions (including design, manufacturing, testing, installation, and field service) – has introduced the GigaGuard GSM-V Controller to replace the GSM-5 Gas Safety Monitor, a legacy technology from the firm‘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 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; and
- 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,” says Dave Stetz, chief engineer of R&D Controls Technology at AES. “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,” he adds. “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.”
