download.
12 V Power Socket
To connect logger to external power supply (negative center).
Sensor Inputs
Pluggable screw terminal blocks marked In-1 to In-4 (from left to right), to
connect wide range of sensor types for data acquisition. All four inputs can be
used simultaneously. Sensors can be connected in any order.
To connect a sensor to the OM-DAQLINK data logger, unplug the screw
terminal, connect the sensor’s wires to the terminals, and then plug the
terminal back to the corresponding socket on the input block.
Excitation socket
Output power socket used to power external sensors, power derived directly
from the external power supply adaptor.
