Digital configurable input/output unit.
● 1 sensor supply voltage 24 V DC, 0.5 A, with short circuit and overload protection
● 24 digital configurable inputs/outputs 24 V DC (C0 to C23) in 1 group (2.0...2.7, 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 supply
voltage of 24 V DC.
All available inputs/outputs are galvanically 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.

NOTICE!
Attention:
All I/O channels (digital and analog) are protected against reverse polarity,
reverse supply, short circuit and continuous overvoltage up to 30 V DC.
The device is plugged on a terminal unit
Chapter 1.5.2 “TU515, TU516, TU541 and TU542
. 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
Chapter 1.8.2.6 “TA526 - Wall mounting accessory”
Connections
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 unit
and always have the same assignment, irrespective of the inserted module:
