Output Applications
The outputs on the Galaxy panels, with the exception of the SPCO relay output, are transistorised outputs;
negative applied (positive removed) by default. These supply up to 400 mA and can be used to drive the
necessary output devices.
NOTE: The polarity of each output can be changed using option 53 = PROGRAM OUTPUTS
Note: For the appropriate 3k3Ω pull-up resistor refer to DIP switch SW3 (Table 2-1).
The relay output is a single pole change over; this can be used to drive output devices that require a clean set
of contacts, isolated from the output voltage.

NOTE: If the output used is one of the panel's
on-board outputs, then substitute this resistor
with a 680 Ω resistor.
