Status LEDs
Five Status LEDs light when associated output is
active(on).
System Communications and Capacity
IEC PELV/NEC® Class 2 wiring connects OMX-IO
interface to processor panel.
Environment
32to104°F(0to40°C).Relativehumidityless
than 90% non-condensing.
Five Input Terminals
•Acceptmaintainedinputsandmomentaryinputs
with 40 msec minimum pulse times.
•Off-stateleakagecurrentmustbelessthan
100 µA.
•Opencircuitvoltage:24V maximum.
•Inputsmustbedrycontactclosure,solidstate,
opencollector,oractive-low(NPN)/activehigh
(PNP)output.
- Open collector NPN or active-low on-state
voltage must be less than 2 V and sink
3.0 mA.
- Open collector PNP or active-high on-state
voltage must be greater than 12 V and
source 3.0 mA.
Five Output Terminals
•Providemaintainedormomentary(1-second)
