Figure 18 NIBP pneumatics diagram
Power supply section of the NIBP board
All connections are established via a 5-pin connector (female). The module needs a +15 V (dirty)
power supply to operate. The supply voltage Vmod 13.8- 16 V is generated in the power supply
section of the monitor. The other voltages needed for the operation of the NIBP measurement
are made on the NIBP board.
The NIBP power supply synchronizes the ECG and STP isolation power and supplies
non-isolated 5 V to the ECG and STP board.
