IWLAN – Client Modules IEEE 802.11n

SCALANCE W748 RJ45 for use in control cabinet

■

Overview

• Suitable for applications where the client module is to be

mounted in the control cabinet

■

Design

• Rugged aluminum enclosure, shock and vibration-proof,

for high mechanical requirements

• Dust protection with IP30 degree of protection

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

• 3 x R-SMA sockets for the connection of directly mountable

and remote antennas (6 x R-SMA sockets for the variants with

two wireless modules)

• Antenna placement optimized for the 3x3 MIMO technology;

the antennas do not interfere with each other when they are

mounted directly on the device

• 1 x RJ45 connector for 10/100/1 000 Mbit/s with Power-over-

Ethernet according to 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

• Digital input for feeding in a signal from a sensor, for example,

to an SNMP-based network management system

• Digital output for converting a command received over SNMP

into a signal and switching a hardware function

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

or on 35 mm standard mounting rail
