A new addition to the Native Series® line of controllers, the NB-GPC3 represents the ultimate in I/O
flexibility. Utilizing American Auto-Matrix’s new STATbus technology, it allows you to customize the
inputs and outputs to wide variety of applications. The NB-GPC3 complies with ANSI/ASHRAE
Standard 135-2001 BACnet.
STATbus is American Auto-Matrix’s innovative new sensor networking technology. STATbus is an open-topology network protocol that allows
flexible connection of up to thirteen I/O devices per channel using a single non-polar, twisted pair cable. This controller has four STATbus
channels. This provides unprecedented flexibility in the installation and wiring of I/O devices to the controller. Substantial saving can be realized in
both wiring and installation costs as compared to conventional sensors. Also, STATbus uses digital communications signals, giving it a higher
level of noise immunity than conventional, analog sensors.
