Terminal CPX-P
Technical data – Output module, digital
Function
Digital outputs control actuators such
as individual valves, hydraulic valves,
heating controllers and many more.
Separate circuits are created using an
additional power supply. Parallel
connection of the outputs of a module
enables consuming devices to be
controlled with up to 4 A.
Applications
Output module for 24 V DC supply
voltage
PNP logic
Module features can be
parameterised
The output module receives the
voltage supply for the electronics
and the outputs from the
interlinking block
Module protection and diagnostics
through integrated electronic fuse
protection in each channel
