5.6 Low Voltage Output Connections
There are two types of Low Voltage outputs: Analog (e.g., 4-20mA) and Transistor based Dry Contact.
The Low Voltage Output connection block is labeled J5 'OUTPUT' (refer to Figure 6). It contains three-
pairs of outputs: Current, Alarm and Motor Status/Stroke.
The Transistor based Dry Contact outputs are optically isolated. To achieve total isolation, they are
not self powered. The external device must supply and detect a return voltage level (32VDC max).
