IWLAN – Access Points IEEE 802.11n

SCALANCE W774 RJ45 for use in control cabinet

■

Overview

• Access points in SIMATIC design suitable for applications

where the device is to be mounted in the control cabinet

■

Design

• Low-profile, compact aluminum enclosure, shock and

vibration-proof for high mechanical requirements

• Implementation of simple and cost-effective wireless machine

networking

• Support of the 2.4 and 5 GHz frequency band

• IP30 protection

• For use at ambient temperatures from -20 °C to +60 °C

• 2 x R-SMA sockets for the connection of direct mountable and

remote antennas

• Antenna placement optimized for the 2x2 MIMO technology;

the antennas do not interfere with each other when they are

mounted directly on the device

• 2 x RJ45 connector for 10/100 Mbit/s, of which one connector

has Power-over-Ethernet compliant with IEEE 802.3at

• 2 x 24 V DC connection for redundant energy supply

• 1 x PLUG compartment for KEY-PLUG/C-PLUG

• Function LEDs for optical signaling of faults/errors and

operating statuses

• Mounting: Wall, S7-1500 mounting rail, S7-300 mounting rail,

or on 35 mm standard mounting rail

• SIMATIC design matches existing components in the control

cabinet (e.g. S7-1500, …)
