SPECIFICATION SUBMITTAL
omx-wci-2 06.01.04
Control Interfaces
OMX-WCI
GRAFIK Systems
Power
• Low-voltage PELV (Class 2)
Operating voltage: 32 VDC.
• Provides 1-way input interface between GRAFIK Lighting
Control Systems and a switch provided by others.
• If using a mechanical switch, it must be a low-voltage, dry
contact closure rated switch.
• If using a solid-state input switch, it must have an on-state
saturation voltage less than 1VDC at 1mA and an off-state
leakage current of less than 1 mA.
• Use with line/mains voltage switches could result in premature
failure of the switch being used.
• If there is any question as to whether a switch is compatible
with these specifications, contact the manufacturer of the
switch.
Key Design Features
• Meets IEC 801-2. Tested to withstand 15kV electrostatic
discharge without damage or memory loss.
System Communications and Capacity
• Low-voltage PELV (Class 2) wiring connects OMX-WCI to
Control Units and other components.
• Up to 32 Wallstations, Control Units, and/or Control Interfaces
may be connected on a PELV (Class 2) Communication Link.
Terminals
Accept up to two 1.0mm
2
(#18 AWG) typical.
Environment
0-40°C (32-104°F). Relative humidity less than 90% non-
condensing.
