Following components are available as accessories for the ET 200M:

• Bus modules for connection/disconnection of modules during operation (hot swapping)
• DIN rail for connection and disconnection of modules during operation
• Covers for backplane bus and bus modules
• Front connectors
• Ex partition for ET 200M
• LK 393 cable guide

Ex partition for ET 200M

Ex partition

A mechanical isolation is required between the IM 153 interface module and the first Ex I/O module. For the hot swapping function, an Ex partition is installed which guarantees the prescribed isolation distance between non-intrinsically-safe and intrinsically-safe areas of an ET 200M remote I/O station.

LK 393 cable guide

LK 393 cable guide

The LK 393 cable duct provides the prescribed isolation between the load voltage input and the intrinsically safe inputs/outputs. The cable duct is easy to fit following insertion of the load voltage inputs L+.

DM 370 Dummy Module

DM 370 Dummy Module

• Reservation of slots for unconfigured I/O modules
• Retention of design and address assignment when replacing by I/O module
