1.11 Connecting an Auxiliary Device
moisture.IQ can power an auxiliary device (such as a loop power transmitter) in which the connection is +24V
to Aux 1 or 2. For external power devices with output directly connected to the auxiliary device, you can use
aux 1 or 2 with respect to RTN (pin 5). Make the connections to the right-side group of probe connections (AUX
IN/OUT
and ALARMS) that are rated for non-hazardous area use. Users set the voltage/current for the auxiliary
input and the electronics will automatically switch the circuits, so the moisture.IQ has no physical switch to
toggle. Figure 23 and Figure 24 below show the connections and wiring for auxiliary devices.
