NS8000 Series
Technical specifications
Supply voltage
9.8 VDC to 16.5 VDC; 15 VDC nominal (from SA bus)
Current consumption
Base current
draw (all
models)
Screen off
18 mA maximum (non-transmitting)
Screen on
45 mA maximum
CO
2
models
13 mA maximum additional current (during measurement)
Note:
SA bus applications are limited to a power load of 210 mA. The best practice when configuring an
SA bus is to limit the total available operating power consumption to 120 mA or less. This power level
allows you to connect a BTCVT Wireless Commissioning Converter temporarily or a DIS1710 Local
Controller Display to the bus for commissioning, adjusting, and monitoring.
