Note:
To prevent damage, do not apply more than 24 VDC to any optoisolator input and verify the correct signal
polarity.
Do not exceed the following voltage and amperage ratings through any relay output:
For outputs 1-12 and Plasma Start: 30 VAC or VDC/1 A. The rating is the same for both AC or DC.
For the brakes 1-4: 30 VDC/1 A or 30 VAC/0.5 A.
For Hold Ignition: 30 VDC/10 mA, polarity is important.
