Digital configurable input / output unit.
● 16 digital inputs 24 V DC in 2 groups (1.0...1.7 and 2.0...2.7)
● 16 digital configurable inputs/outputs 24 V DC (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 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.
