3 Functions and features
The unit monitors the system pressure of machines and installations�
Applications
Type of pressure: relative pressure
Order no. Measuring range
Permissible

MPa = bar ÷ 10 / kPa = bar × 100
Avoid static and dynamic overpressure exceeding the given overload
pressure by taking appropriate measures�
The indicated bursting pressure must not be exceeded�
Even if the bursting pressure is exceeded only for a short time, the unit
may be destroyed� NOTE: risk of injury!
Use in gases at pressures > 25 bar only on request�
4 Function
4.1 Communication, parameter setting, evaluation
• The unit displays the current process value�
• It generates 2 output signals according to the parameter setting�
OUT1 • Switching signal for process value; IO-Link�
OUT2
2 options
• Switching signal for process value�
• Diagnostic signal (output 2 is inactive in case of a fault)�
• The following functions are available via IO-Link (OUT1):
reading the current process value, changing the parameters and transferring
them to other units of the same type using parameter setting tools with IO-Link
capability (except the FDT service program ifm Container)�
