3.6.1 Functionality

The I/O terminal units TU582-S (with spring-type terminals) is specifically designed for use with
AC500-S safety I/O modules AI581-S, DI581-S and DX581-S.
The safety I/O modules plug into the I/O terminal unit. When properly seated, they are secured
with two mechanical locks. All the electrical connections are made through the terminal unit,
which allows removal and replacement of the I/O modules without disturbing the wiring at the
terminal unit.
The terminals 1.8 to 4.8 and 1.9 to 4.9 are electrically interconnected within the I/O terminal unit
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
The assignment of the other terminals is dependent on the inserted safety I/O module
Ä DI581-S Ä DX581-S Ä AI581-S.
