Wire Hookup
In a three-wire hookup, the transmitter can be wired two ways depending on load “sinking” or
“sourcing”. At least 14 VDC is required for operation.
Depending on how the transmitter is mounted, route the DC power, analog output, and wiring
into the transmitter as follows:
• Wall/Pipe-mounted Transmitter: Route cable through right side cable entry knockout
hole in the back cover.
• Panel-mounted Transmitter: Route cable behind panel to the exposed TB1 terminal
strip.
• Integral Sensor-mounted Transmitter: Route cable through right side cable entry
knockout hole in the back cover. (Do not open left side cable entry knockout hole in
cover).
Wiring Tip! Use high quality, shielded instrumentation cable.
