Eaton - Lighting Systems iLight Product Series - UIG-2 73-898-00 IM8840 Iss.02 3
Specification
Inputs
4 Optically-isolated digital inputs
A. Requires 5 - 24 Vdc supplied from +12V_
opto to 0V_opto terminals
B. Optical isolation offers improved
performance in electrically noise environments
C. Internal 12Vdc current limited (50mA)
supply available where an external supply is
not required; using this supply requires
by-passing the optical isolation of these inputs
D. Opto-isolated digital inputs work with:
1. Switch closure from the IN_opto to 0V_opto
• For use with both momentary and
maintained inputs
• Minimum momentary input pulse
duration 20 msec
• Switch will see up to 16mA when
closed
2. Open collector NPN active low circuit
• On-state voltage ≤ 1 volt and
capable of sinking 16 mA
• Collector-emitter leakage current ≤
500 nA
• Collector-emitter voltage ≥ supply
voltage
3. Actively driven circuit
• Active low voltage ≤ 1 volt and
capable of sinking 16 mA
• Active high voltage ≥ supply – 0.25
volts
E. All opto-isolated digital inputs wire with 2
part connectors with screw terminals. Wire
sizes 4mm2 (12 AWG) to 0.25mm2 (24 AWG).
4 Analogue / digital inputs
A. Individually programmable as analogue or
digital inputs
B. 5Vdc & 12Vdc current limited (50mA total)
regulated supplies available for analogue /
digital input devices
C. Analogue input mode:
1. Suitable for use with rotary and linear
variable resistors
2. Reads input voltages from 0 – 10 Vdc
3. Inputs protected for use up to 12 Vdc
D. Digital input mode works with:
1. Switch closure from the IN_A/D to 0V_A/D
• For use with both momentary and
maintained inputs
• Minimum momentary input pulse
duration 20 msec
• Switch will see up to 60uA when
closed
2. Open collector NPN active low circuit
• On-state voltage ≤ 500mV and
capable of sinking 60uA
• Collector-emitter leakage current ≤
10 uA
• Collector-emitter voltage ≥ supply
voltage
3. Actively driven circuit
• Active low voltage ≤ 500mV and
capable of sinking 60uA
• Active high voltage ≥ supply – 1 volt
4. All analogue / digital inputs wire with 2 part
connectors with screw terminals. Wire sizes
4mm2 (12 AWG) to 0.25mm2 (24 AWG).
