Figure 4-35 SCALANCE W778/W738
The access point and client devices of the SCALANCE W778/W738 product group are
designed for easy and cost-effective wireless machine networking. They support the IEEE
802.11n standard and use the 2 x 2 Single-User MIMO antenna technology that reaches a
data transmission speed of up to 300 Mbps. A redundant power supply and the PoE
connection is part of the standard equipment of the devices. The devices are therefore
suitable for applications with high requirements on reliability. iFeatures can be added with
the optionally available KEY-PLUG; real-time data transfer will then also be possible.
All devices have a shock- and vibration-resistant aluminum housing with screwed
connections. The devices can therefore be used in areas of application with high
requirements on mechanical stability.
The devices are designed in IP65 degree of protection for the installation without cabinets
and can be directly mounted on a standard DIN rail or directly on the wall.
The EEC variants have coated PCBs and can be used in extended temperature ranges as
well as in railway applications.
The following variants exist:
● SCALANCE W778-1 M12
Access Point
● SCALANCE W778-1 M12 EEC
Access point with coated PCBs
● SCALANCE W738-1 M12
