Power Supplies

The 1771 backplane provides the power for most of the module circuits. You’ll

need external power supplies for the analog outputs, transducer interfaces,

discrete inputs and discrete outputs.

All four power supplies and their associated module circuits are electrically

isolated from the I/O chassis and from each other. To provide maximum

isolation of the four sets of circuits, the four supplies should be from separate

sources. However, you can use the same power supply to power two or more

circuits if you don’t need the isolation that separate supplies provide.

Information on how to connect the power supply for each circuit is under the

heading for that circuit.

Figure 5.7 shows the transducer interface connections. You should refer to the

wiring diagrams supplied with your transducer to determine pinouts on the

transducer head.

Important: The transducer must be configured for external interrogation.
