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.
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 3k3
Ω 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.
