1.4.4 Relay Output Connectors
The PCT provides two 120VAC silicon relay outputs or two DC Sink (NPN) relay outputs. These connectors are
not intended to be used by the customer. They are used by ALI to control various optional PCT add ons, such as
the red / yellow stack light.
When the PCT is ordered with the optional red / yellow stack light, the Ha 120VAC relay output controls the red
light, and the Hb 120VAC relay output controls the yellow light.
The DC Sink relay outputs are reserved by ALI for future feature expansions to the PCT.
Note: Do not connect any wiring to the 120VAC or DC Sink relay output connectors unless directed to do
so by American Led-gible Inc.
