Power and Current Requirements

Power

10 to 14 VDC @ 3.0 A (maximum current draw for a fully loaded GIOX unit)

 

Current

Mother Board

Output Module

• 300 mA per Output Module

 

Output Relay Contact Rating

• 1 A @ 24 VDC

 

Operating Conditions

• 32°F to 150°F (0°C to 60°C) – 0% to 90% relative humidity, non-condensing

 

RS-485 Cable Options

The current demands of the GIOX motherboard, requires the GIOX unit be the only unit on the RS-485 bus line. The total cable run distance should be no more than 500 feet from the controller (if the GIOX is being powered from the controller). If the GIOX module has its own, local power-supply and you are using Belden 9501 cable then the maximum cable run distance is 1200m/4,000feet.


Note: If you are powering the GIOX from the controller (if only input modules are used)Cable resistance causes a drop in voltage at the end of long cable runs. Ensure the

appropriate power and current for your device is available at the device at the end of the cable run.

Heavier gauge cable reduces this affect.


RS-485 bus runs can daisy-chain together an NXT-GIOX and NXT-Reader on one line. The total cable run distance should be no more than 500 feet from the NXT controller for runs with GIOX modules and no more than 1,000 feet for reader-only runs.

  1. To meet CE and C-tick regulations, the length of the controller power line can be no longer than 3 Meters (9.85 feet).
  2. Use the shortest possible path from earth ground point to PCB. Connect the earth ground only to the designated pin on the terminal block. This is important as all transient protection for the unit is made through this earth ground connection. For unit protection, the earth ground connection should always be made first.
  3. Values listed are minimums. Individual input and output devices may have more specific requirements.

Notes: 
  1. The Lock Output relay may require a heavier gauge of wire depending upon the current demands of the lock and the length of the lock wiring run.
  2. Cable resistance causes a drop in voltage at the end of long cable runs. Ensure the appropriate power and current for your device is available at the device at the end of the cable run. Heavier gauge cable reduces this effect.
  3. Keri does not recommend hot-plugging a Reader, RIM, GIOX or 4x4 into an NXT controller Intelliprox Blue controller. Remove power from the controller prior to connecting these devices.
