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)
3 mA maximum (non-transmitting)
CO
2
models
25 mA maximum additional current (during measurement)
Display models - backlight on
30 mA additional current
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.
