LRP2000 Long Range Passive Reader/Writer
Outputs
The output is limited to 30Vdc 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(e.g. an
incandescent light). The inductive "kick" (back EMF from a collapsing
magnetic field) when a relay is released can impose a voltage higher
than 30V and destroy the output transistor (use a backwards diode to
clamp the back EMF).
