Chapter 1.4.3 “TU515,
TU516, TU516-H and TU542 for I/O Modules”
on page 153
Electrical Connection
The modules are plugged on an I/O terminal unit
Ä
Chapter 1.4.3 “TU515, TU516, TU516-H
and TU542 for I/O Modules” on page 153. Properly position the modules and press until they
lock in place. The terminal units are mounted on a DIN rail or with 2 screws plus the additional
accessory for wall mounting (TA526
Ä
Chapter 1.8.2.4 “TA526 - Wall Mounting Accessory”
on page 1152).
The electrical connection of the I/O channels is carried out using the 40 terminals of the I/O ter-
minal unit. I/O modules can be replaced without re-wiring the terminal units.
For a detailed description of the mounting, disassembly and electrical connec-
tion of the module, please refer to the System Assembly, Construction and Con-
nection chapter
Ä
Chapter 2.6 “AC500 (Standard)” on page 1248.
The terminals 1.8 to 4.8 and 1.9 to 4.9 are electrically interconnected within the I/O terminal
units and have always the same assignment, independent of the inserted module:
Terminals 1.8 to 4.8: process voltage UP = +24 VDC
Terminals 1.9 to 4.9: process voltage ZP = 0 V
The assignment of the other terminals:
