Gateways, Data Concentrators, & RTU's

QEI produces a wide variety of Gateways, Data Concentrators, and RTU's.  They can be used for
• Connect and communicate with your substation IED's or down-line feeder devices
• Convert IED protocols to communicate with your EMS/DMS/SCADA system protocol
• Upgrade legacy RTU's
• Establish peer-to-peer communication paths within a substation
• Integrate IED and discrete I/O through one unit
