Connecting Pressure Sensor Amplifiers

3.2.1

FT40

The input signal from the pressure sensor amplifier is connected to pins 5 (A-FB) and 16 (SG)
on the I/O signal connector (CN1).
Type
Input
The input specifications are as follows:
• Maximum input voltage: ±12 V
• Input voltage resolution: ±10 bits
• Input impedance: 30 kΩ
SERVOPACK
Implement the following countermeasures against noise to prevent inductive noise.
• Use twisted-pair cables.
• Minimize the connection distance.
• Attach a ferrite core.
Recommended Pressure Sensor Amplifier Specifications
• Output voltage: ±12 V
• Response frequency: 500 Hz min.
3.2.2

FT41
