Required Terminal Unit
TU515 or TU516 Ä Chapter 1.4.3 “TU515, TU516, TU516-H
and TU542 for I/O Modules” on page 153
1.6.2.1.3 Electrical Connection
The function module CD522 can be connected to the following devices via the I/O bus con-
nector:
● CS31 bus module DC551-CS31
● Processor module PM5xx
● Other AC500 I/O devices.
The electrical connection is carried out by using the 40 terminals of the Terminal Unit TU515/
TU516 Ä Chapter 1.4.3 “TU515, TU516, TU516-H and TU542 for I/O Modules” on page 153.
