Buffered Outputs
Along with the BNC outputs, a buffered output is provided for each channel
(0...3) on the upper module connector.
Although having independent resistive current limiting, the buffered and BNC
outputs of any one channel share drive circuitry. All signal-related inputs and
outputs, unless otherwise indicated, share analog ground/return.
Lower Module Connector
The following are functions of the lower module connector.
Sensor Connections
The sensor connections are made on the lower module connector.

Yes
For permanent connections to instruments or when long
cable runs (100 m/328 ft) are required.
Notes
All outputs are single ended and have no isolation.
Buffered output is not representative of input when no load (sensor) is connected to the associated
measurement channel.
Confirm that the connected instrumentation does not provide power, such as if to power an
accelerometer, to the buffer output.
