-Low Smoke Zero Halogen (Type 1 LSZH): Suitable for scenarios with requirements for smoke toxicity and corrosiveness (such as subways, data centers)

Cable interface module side: 37 pin D-subminiature (D-type) interface; TA side: 25 pin D-subminiature interface

2. Installation requirements

Specific requirements for installation category

The module installation needs to be installed on a 200 series standard modular base plate (such as RH101KF), which supports horizontal/vertical DIN rail installation or can be adapted to a 19 inch rack through an installation kit; Can be installed on the same substrate as other 200 series FBM modules

TA can be installed independently on 32mm or 35mm DIN rails, and can be installed in the same cabinet or adjacent cabinets with the module (the terminal cable supports a maximum length of 30m)

The wiring specifications support solid/multi strand wires (wire diameter 0.2~4mm ²/24~12AWG), and multi strand wires with wire ears (wire diameter 0.2~2.5mm ²) can also be adapted
