Power

USB +5 V input voltage range: 4.75 V to 5.25 V

USB +5 V supply current: All modes of operation: 10 mA max

External power input: 9 V nominal

External power supply (required): MCC p/n CB-PWR-9: 9 V @ 1.67 A

Voltage supervisor limits - PWR LED

6.5 V > Vext or Vext > 12.5 V: PWR LED = Off (power fault)

USB-PDISO8 Series devices monitor the external +9 V power supply voltage

with a voltage supervisory circuit. If this power supply exceeds its specified

limit, the PWR LED turns off, indicating a power fault condition.

6.5 V ≤ Vext < 12.5 V: PWR LED = On

External power consumption

All relays on, 100 mA downstream hub power: 820 mA typ, 900 mA max

All relays off, 0 A downstream hub power: 200 mA typ, 230 mA max
