Emerson Process Management adds Power over Ethernet (PoE) to the Smart Wireless Gateway 1420, making it possible to power the gateway and compatible devices using a standard Ethernet cable. PoE allows installation of wireless gateways without requiring extra power wiring infrastructure.
The PoE gateway provides infrastructure flexibility in places where there is limited access to power. By using an Ethernet cable connection, a new PoE gateway can be easily installed and powered by an existing wireless access point. Alternately, PoE allows the gateway to power any Ethernet-enabled instrument.
