Eaton MTL ExLAN intrinsically safe ethernet OEM interface

Please note that this product has been discontinued.

The Crouse-Hinds series MTL ExLAN is an intrinsically safe (IS)

10/100Mbps Ethernet Interface incorporating CSLs patented

technology. This module is intended to simplify OEM product

design and certification. It ensures full IS compatibility of

interconnected devices including the current range of MTL 9400

IS Ethernet modules and future product ranges.

As well as providing the essential network LAN interface,

the module also voltage-clamps the equipment’s main supply rail

(typically 5V or 3V3) together, ensuring that the generated

Ethernet signals are limited to low Intrinsically Safe levels.

It is fully compatible with PoExTM (12VDC Power over Ethernet

for Hazardous Areas).

Certifications and compliances

• Intrinsically Safe ATEX / IECEx Component Certification

• Ex ia IIC T4 Ga

• Ex ia IIIC T135°C Da (non-mining)

• Ex ia I Ma (M1 mining)

• Ta = -40ºC to +70ºC

Design features

• PoExTM Compatible (Power over IS Ethernet) 10/100 BASE-T IS

Ethernet Interface for standard Cat5e/Cat6 Ethernet Cabling Systems

• Voltage Clamping (Duplicate OVP crowbar circuitry) clamps users

5V or 3V3 supply rail to 5.88V maximum

• ExLAN interface connects between the Ethernet port Magnetic

(transformer) and RJ45 (or other) connector

• Magnetic can be omitted if not required and ExLAN module then

connects directly to PHY

• Compact design at 40mm x 40mm x 8mm for easy installation

• -40°C to +70°C operating temperature, designed for harsh

environments
