Guardian Wireless Module
Designed for today's high speed serial SCADA & Telemetry applications, Guardian wireless modems provide a transparent 19200 bps serial digital link in a 25 kHz channel, or a 9600 bps digital link in a 12. 5 kHz channel that is compatible with most protocols. Selectable operating modes. A guardian module is add-on hardware that incorporates an Azure Sphere chip and physically attaches to a port on a "brownfield" device—that is, an existing device that may already be in use. The Guardian-400 Serial or. Guardian Industrial Grade Serial Wireless Modem and Analog Radio. Selectable operating modes provide flexibility: RS-232, RS-422, and RS-485 compatible; simplex, half-duplex or. We will introduce you to Advantech's new joint product with Microsoft, WISE-4250AS, a dual-band industrial WiFi I/O module with Azure Sphere. You will get a better understanding of how Advantech brings the high-security requirements of the Internet of Things to the industrial control field through.

Relay Protection Generator Demagnetization Causes
It is caused by accidental tripping of field breaker, short circuit in the field circuits, poor brush contact or operating errors. The rotor of the generator loses the excitation current. After the generator loses its magnetism, it will cause the generator to lose step, and will generate differential frequency current in the rotor's dam ping winding, rotor surface, and rotor winding, causing additional temperature rise, which. Protecting a generator requires more than just a single relay. It's a system that includes auxiliary relays, communication with SCADA or similar systems, wiring from CTs and PTs (sometimes called VTs), and protective relays, which can be standalone devices or part of multifunction units.
