3.8.2 Outputs

The output is limited to 30 VDC when off and 500 mA. These are maximum ratings. A device that operates at 200 mA may destroy the output due to inrush current if that current exceeds 500 mA (such as an incandescent light). The inductive kick (back EMF from a collapsing magnetic field) when a relay is released can impose a voltage higher than 30 V and destroy the output transistor (use a backwards diode to clamp the back EMF).
