Figure 2-7. Relay logic jumpers JP5 and JP6
shows SSR modules 1-4 set to invert logic (active high), and modules 5-8 set to non-invert logic
(active low).

The I/O type and the relay logic settings control what happens when a module activates. For example, a module
group configured for SSR input with non-inverted logic outputs a low logic level when the module is ON. A
module group configured for SSR output with non-inverted logic requires a low logic level to turn the output
module ON.
