Digital configurable input / output unit.
● 16 digital inputs 24 VDC in 2 groups (1.0...1.7 and 2.0...2.7)
● 16 digital configurable inputs/outputs 24 VDC (C16 to C31) in 1 group (3.0...3.7 and
4.0...4.7), of which each can be used
– as an input,
– as a transistor output with short circuit and overload protection, 0.5 A rated current or
– as a re-readable output (combined input/output) with the technical data of the digital
inputs and outputs.
● Optional with fast counter
The configuration is performed by software. The modules are supplied with a process voltage of
24 VDC.
All available inputs/outputs are electrically isolated from all other circuitry of the module. There
is no potential separation between the channels within the same group.
For use in extreme ambient conditions (e.g. wider temperature and humidity range), a special
XC version of the device is available.

TU516, TU516-H and TU542 for I/O Modules”
on page 153
Effect of incorrect input terminal connection Wrong or no signal detected, no damage up to
35 V
The device is plugged on a terminal unit
Ä
Chapter 1.4.3 “TU515, TU516, TU516-H and TU542
for I/O Modules” on page 153. Position the module properly and press until it locks in place. The
terminal unit is either mounted on a DIN rail or to the wall using 2 screws plus the additional
accessory for wall mounting (TA526

on page 1152).
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
