The maximum voltage that can be applied to the digital switch outputs is 30 VDC. This is an
open circuit parameter (the digital switch is in the open state). Under open circuit conditions, the
switch current will be less than 0.200 mA.
The switch maximum current rating is 1 A. When the switch is ON, the typical switch voltage is
≤ 1V.
When the switch is on (closed) the external voltage must be dropped across the load (Figure
33).
CAUTION
The load must be designed such that the
current in the circuit is ≤ 1 A at all times. Some
3rd party devices, such as incandescent lamps
or solenoids, require surge and back EMF
protection to prevent voltage spikes.
Inductive Load, Solenoid, Incandescent Lamp Configuration
Load is designed to limit current through the switch to 1A.
