Power Connector
2-pin terminal block for DC power input. Use a Safety Extra Low Voltage
(SELV) compliant limited power source (LPS) with either a rated output
power limited to ≤100 W or a rated output current limited to ≤5 A.
When used in systems that require UL certification, the product shall
be powered by a UL 294-listed or UL 603-listed Class 2 low-voltage
power limited power supply.
Notes
For powering auxiliary equipment.
Note: This pin can only be used as
power out.
Digital input — Connect to pin 1 to
activate, or leave floating (unconnected)
to deactivate.
Digital output — Connected to
pin 1 when activated, floating
(unconnected) when deactivated. If
used with an inductive load, e.g. a relay,
a diode must be connected in parallel
with the load, for protection against
voltage transients.
