Dial-Up Access—Add dial-up or dial-out communications via the USB standard-B connector or EIA-232 port. Integrate the SEL-9192 to provide dial-out supervisory control and data acquisition (SCADA) communications, dial-up engineering access through an information processor, and direct access or polling to intelligent electronic devices (IEDs), remote terminal units (RTUs), industrial equipment, or field devices.

Modem Pool—With the SEL-3610 Port Server, create a modem pool with as many as eight port-powered SEL-9192 Modems and nine additional externally powered SEL modems.

Utility-Grade Quality—Deploy the SEL-9192 in harsh environments with utility-grade specifications for rugged reliability and a wide temperature range.

Flexible Input Voltage Options—Power the SEL-9192 through the USB or serial ports or with an external power supply.
