SCALANCE W774 M12 EEC for enhanced environmental conditions

■

Overview

• Suitable for use in industrial and automation applications

in general, but especially in railway 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

• Special coating of the printed circuit boards (conformal

coating)

• Resistant to condensation

• Railroad approval in accordance with EN 50155

• IP30 degree of protection

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

• Support of the 2.4 and 5 GHz frequency band

• 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 M12 connection for 10/100 Mbit/s, of which one

connection with Power-over-Ethernet according to

IEEE 802.3at

• 1 x M12 socket for power supply (24 V DC)

• 1 x PLUG compartment (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
