Mechanical and Electrical Configuration
This section discusses the following aspects of an ET 200U distributed I/O
station:
Installing a station mechanically
Wiring a station
Installing a station electrically
The degree to which you can expand a slave station is limited by the follow-
ing factors:
The number of modules you can connect
(a maximum of 16 bus units or 32 modules)
The addressing range of an ET 200U slave station
(a maximum of 32 input bytes and 32 output bytes)
The current consumption of the individual modules
(total current consumption from 9 V DC, I/O bus
700 mA at 60
C
900 mA at 40
