Buffered Outputs
Back Side Buffered Outputs
On the back of each CMM + PRM slot there are 16 buffered analog outputs
marked as "Buf A" and 8 buffered digital outputs marked as "Buf D" as shown
in Protection Module (PRM)Protection Module (PRM)Protection Module
(PRM)Protection Module (PRM)Protection Module (PRM)Protection Module
(PRM)Protection Module (PRM)Protection Module (PRM).
•
The buffered analog signal is divided by 2.
The measuring instrument connected to these buffered outputs must
compensate for this. This can be done by using a sensitivity that is 50% of the
connected sensor. For example, if the sensor is 100 mV/g, then set the
sensitivity on the measuring instrument to 50 mV/
g.
•
The buffered analog outputs are maximum ±11 V and cutoff frequency (-3
dB) is at 60 kHz
•
The buffered digital outputs are 5 V TTL signal.
