Flange module for safety functions VABP
The flange module VABP for safety functions serves as an interface for safe venting in an emergency.
The use of control valves makes it possible to implement safety functions (HFT 0, HFT 1) for safe
venting with various safety architectures. Exhaust duct 2 of the mounted control valve is always
directly connected to duct 2 of the pneumatic drive, independently of other modules and module
positions of the valve terminal VTOP.
The flange module for safety functions VABP only provides the interface for various safety architec-
tures and is not a safety device.
The safety-related values are dependent on the specific control valve and the selected safety architec-
ture.
