Appendix D - GPIO Pinouts
GP Outputs
All output switch closures are via DIL relay.
DO NOT use these outputs to directly switch capacitive or reactive loads; always use a separate
external relay with suitable contact rating.
DIL Relay Ratings:
• 100V DC, 125V AC
• 100mA max.
GP Inputs
Inputs are triggered by applying an AC or DC voltage of between 4V and 24V. The current drawn is
approximately 10mA. Minimum input pulse duration 50mS.
