+12V < 20mA Output
The i .LON 100 server contains one +12V outlet that can provide up to 20mA.
This +12VDC connection may be used by a set of dry contacts to power the
optically isolated digital inputs connected to the digital input screw terminal
connectors.
The +12V <20mA output is implemented on screw terminals 19 and 20. Screw
terminal 20 is the +12 Volt power connector. Screw terminal 19 is the system
ground.
Figure 1.12 shows the 12V <20mA output screw terminals.
