Connections
For a detailed description of the mounting, disassembly and connection of the
module, please refer to the System Assembly, Construction and Connection
Chapter 2.6 “AC500 (Standard)” on page 971.
The modules are plugged on an I/O terminal unit
Chapter 1.5.2 “TU515, TU516, TU541 and
TU542 for I/O modules” on page 126
. 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
Chapter 1.8.2.6 “TA526 - Wall mounting accessory”
The connection of the I/O channels is carried out using the 40 terminals of the I/O terminal unit.
I/O modules can be replaced without re-wiring the terminal units.
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 V DC
Terminals 1.9 to 4.9: process voltage ZP = 0 V DC

For the open-circuit detection (cut wire), each analog input channel is pulled up
to "plus" by a high-resistance resistor. If nothing is connected, the maximum
voltage will be read in then.
