Single Power Supply Configuration

Single Power Supply Configuration

Overview This section contains illustrations of a sample circuit layout, potential bundling, and potential isolation for a single power supply configuration.

Fusing in Circuit Layout Each of the following circuit branches must be fuse-protected (F in the figure below). In the case of long lines, the circuit branch must be provided with a suppressor circuit OVP001/OVP 248. This protection selectively shuts off a circuit branch through the associated fuse even if the diode is short-circuited.

Illustration The following illustration shows a sample circuit layout for a single power supply configuration.

F automatic circuit breaker or fuse (see appropriate field wiring illustration in I/O base description) F10 optional circuit breaker (with over-voltage protection) PS power supply 24 VDC, max. 25 A V1 overvoltage protection circuit OVP001, OVP002

Fusing in Wiring Illustrations The fuses shown in the illustrations below must be selected on the basis of the type and number of the sensors and actuators used.

Potential Bundling In this example, the output voltage is drawn from a separate power supply.

Potential Isolation In this example, the output voltage is drawn from a separate power supply
