The analog input module has the following mechanical properties:

Compact design
Rugged plastic enclosure in include:

Group fault indication red light
Front connector plug options, installed behind the front door and get protection.
Label area on the front door.
Connection pin assignment is for the internal wiring in the front door.
Easy to install
Modules are mounted on a DIN rail and connected to adjacent modules through the bus connectors. No slot rules; the input address is determined by the slot.

When used in the ET 200M distributed I / O system with active bus modules, plc digital input output module are hot-swappable, without any response. Other modules continue to work.

User wiring
Device unit is connected via the front connector. When the first connection module, the encoding device is locked in the connector, so that the connector can only be adapted to the same type of module. When replacing modules of the same type for the new module can be left intact to maintain the state before wiring connector. This avoids the process of replacing the plc module will be wired front connector into the wrong module.
