Refer to the specific sensor documentation for terminal connection details and use the pinout diagram on
page 69 to connect a two- or three-wire sensor or transducer to the module’s terminals.
Figure 6:
Connect Analog Sensors
Steps
To make the connection:
1.
Loosen the screw for each pin on the connector.
2.
Insert the appropriate wire.
Make sure all wires attached to the Analog Sensor Port are routed through the cable access
opening.
3.
Tighten the screw.
Note on Cables
To fit into the holes in the rubber cable channel, the ideal cable diameter is 0.157 in (4.0 mm). If the
cable is too small, build up the diameter using heat shrink. If it is too big and you are using the secondary
cable access opening, then place the cable through the left-most hole in the rubber cable channel where
the diameter can be up to 0.25 in (6.4 mm).
If you are not using the secondary opening or the cable is still too big, then splice on another cable with a
smaller diameter to fit through the hole. See the steps later in this section for working with the rubber
cable channel.
