APPLICATION EXAMPLE 2: FIELD
TERMINATING DEVICES DIRECTLY TO
CONTROLLERS
The following examples show how
switches can be connected directly to a
controller. This is often desirable when
fewer than 12 switches are required.
The three position push-button switch, in
this example, contains pilot lights in each
position. As wired (directly across the 15
Volt supply) the pilot lights will always be

on. The dotted lines imply that the pilot lights
are wired together inside the wall-box. As
shown there are NO current limiting
resistors as the specified switch has
internal current limiting. Also of interest is
that all the pilots and switches share a
single common. These can be combined in
the wall-box to reduce the number of
conductors required to pull.
The SOC has the same inputs as described
above for the USC. The differences being
the connectors are located along the left
edge of the controller.
SPECIAL NOTE: Notice that the momentary
switch is wired to ANALOG IN #1 (UI1).
This is because maintained closures during
power-up will force the controller into a
special override mode. SIMPLE RULE: When
connecting switches to analog inputs –
never use maintained contacts on Analog
Input #1, especially if there is a chance that
the contact will be closed during controller
power-up.
