Power Supply
In some applications the MOPSlcdLX is intended for use as a stand-alone module without a backplane. You
need to have a power connector available on the board for direct power supply. The MOPSlcdLX is a +5V
only board. Peripherals can obtain additional voltage from the power connector next to the PC/104 bus.
The additional voltages (+12V, -5V and -12V) are not generated onboard.
17.1
Connector
The power connector is available as X10000C (8 pins).

Note:
To protect the external power lines of peripheral devices make sure that
1)
- the wires have the right diameter to withstand the maximum available current.
- to enclosure of the peripheral device fulfills the fire-protecting conditions of IEC/EN 60950.
17.2
Power Pins
Every power pin on the power connector supplement is limited to a maximum current and the following
limitations apply:
Note:
The MOPSlcdLX is not a replacement for a backplane. Use all power pins on the power connector and on the PC/104 con-
nectors for power supply to the MOPSlcdLX and also use all additional power connectors on additional I/O cards if your
system exceeds the above limitations. It is not acceptable to use only the power pins of the PC/104 connector for power
supply to the full PC/104 stack.
