Contact Closure Wiring
Contact Closure Ratings
Five Input Terminals
• Accepts maintained inputs and momentary inputs with 40 ms
minimum pulse times.
• Off-state leakage current must be less than 100 μA.
• Open circuit voltage: 24 V
• Inputs must be dry contact closure, solid state, open collector,
or active-low (NPN)/active high (PNP) output.
– O pen collector NPN or active-low on-state voltage must be
less than 2 V and sink 3,0 mA.
– O pen collector PNP or active-high on-state voltage must be
greater than 12 V and source 3,0 mA.
• Lutron recommends a maximum of 3 occupant sensors wired
in parallel per input.
Five Output Terminals
• Provide selectable maintained or momentary (250 ms) outputs.
• The interface is not rated to control unclamped, inductive loads.
Inductive loads include, but are not limited to, relays, solenoids,
and motors. To control these types of equipment, a flyback
diode must be used (DC voltages only). See diagram below.
• Output relays are non-latching (i.e. if relays are closed and
power is lost, relays will open).
