ET 200X Distributed I/O Device
EWA 4NEB 780601602-06
Note
The following applies to the BM 143-DESINA FO, BM 143-DESINA RS485, and
EM 143-DESINA modules:
All inputs receive the non-switched load voltage.
Outputs (if present) of sockets X1, X3, X5, X7 are supplied by the switched
load voltage.
Outputs (if present) of sockets X2, X4, X6, X8 are supplied by the
non-switched load voltage.
The outputs of all other expansion modules receive the switched load voltage.
Protection against destruction of components
In order to prevent the components of the ET 200X from being destroyed, you
must always protect the supply voltage lines to the electronics/sensors and the
load voltage with an external circuit–breaker – for example, Siemens Series 5SN1
that has the following characteristics:
Protection of the supply voltage for the electronic components/sensors:
230 VAC (with rated current)/max. 6 A: tripping characteristic (type) B or C
Protection of the load voltage:
230 VAC (with rated current)/max. 16 A: tripping characteristic (type) B or C
