Output Applications
The outputs on the GX-Series panels, with the exception of the SPCO relay output, are transistorized
outputs; negative applied (positive removed) by default. These can switch up to 400mA and can be used to
drive the necessary output devices.
NOTE: The polarity of each output can be changed using option 53 = PROGRAM OUTPUTS
Common Collector Output
+12 V
Use 3.3k Ohm resistor for
open-collector output
Note:
For the appropriate 3.3kΩ pull-up resistor refer to DIP switch SW3 (Table 2-1).
The relay output is a single pole change over (SPCO); this can be used to drive output devices that require a
clean set of contacts, isolated from the output voltage.

Trigger Header
The Trigger Header on the GX-Series is a set of pins that consist of programmable outputs for an external
communication module. The connection is via an optional ribbon cable.
Trig 1-6
There are six trigger outputs that can be used as communication triggers, but can also be used for any other
purpose. By default these outputs are programmed as positive. They are designed to sink current (to 0V) not
source current (from 12V). The functions of these outputs are shown in Table 2-9:
