The MT16-2G module rack consists of a backplane, two PS-F24Ex mains filters and the actual rack system. It can accommodate 2 gateways, 2 power supply units as well as 16 I/O

modules. Up to 128 binary inputs/outputs or

64 analog inputs/outputs resp. a mix of both

can be connected to it. Two PS-F24Ex mains

filters are mounted on the module rack. The

mains filters filter the 24 VDC voltage and protect against induced interference in the supply

cable.

All modules can be plugged and unplugged

under power without interrupting the data

transmission. The same applies to redundant

gateways and power supply modules.

The module rack is designed in a combined

protection rating of Ex e and Ex i and can

therefore be used in zone 1.

The power supply of modules on the backplane is limited to prevent sparking. This allows you to pull and plug modules in powered

state with excom? mounted in zone 1.

The rack system is made of continuously cast

aluminum. This ensures increased stability

and shielding. The module rack is suited for

switch cabinet and 19 rack mounting.

■ Module rack for max. 16 I/O modules, 2

gateways and 2 power supply modules

■ The terminals for the signal connection level are available as accessories
