Wiring And Connecting Analog, Digital I/O, And Sdi-12 Devices; Flow Signal Cable Wiring - YSI ProSample Series User Manual

Wiring and Connecting Analog, Digital I/O,
and SDI-12 Devices
The ProSample P and ProSample PM can be configured to sample based on measurements/signals from analog and
digital I/O devices, while the ProSample P-12 and ProSample PM-12 can additionally be configured to sample based
on measurements from SDI-12 devices (e.g. EXO3 sonde).

Flow Signal Cable Wiring

The flow signal cable (item # 630147) can be used to send a digital, analog, or event signal to the ProSample. One
end of this cable has flying leads so it can be connected to an analog and/or digital device, while the other end can be
connected to the Signal Input on the ProSample. Please refer to the wire colors below when connecting the flow signal
cable to the digital and/or analog device.

NOTE: An analog and digital device can be connected to the ProSample using the flow signal cable.
NOTE: The green and common (grey) can be connected to a relay connection. When the relay closes, an event is
triggered and sampling will start.
