In many cases, using the built-in aux24VDC supply can result in a cost
savings for your control system. It can power combined loads up to 500 mA, which is
enough to eliminate the need for an additional power supply in some applications. If
you are the system designer for your application, you may be able to select and
design in field devices which can use the +24VDC auxiliary supply.
All AC-powered DL105 Micro PLCs feature the internal auxiliary supply. If input
devices AND output loads need +24VDC power, the auxiliary supply can power both
circuits as shown in the following diagram.

DC-powered DL105 Micro PLCs are designed for application environments in which
low-voltage DC power is more readily available than AC. These include a wide range
of battery--powered applications, such as remotely-located control, in vehicles,
portable machines, etc. For this application type, all input devices and output loads
typically use the same DC power source. The F1-130DR-D and F1-130DD-D are
compatible with 12VDC or +24VDC systems. Typical wiring for DC-powered
applications is shown in the following diagram.
