Information About B3920BCM-MS/TP
The B3920 is an integral BACnet Advanced Application Controller (B-AAC) belonging to the renowned Andover Continuum series. It features a high-density I/O architecture enclosed within a rugged panel-mount chassis, providing technicians with the flexibility to directly manage numerous motorized valves, actuators, and plant sensors without requiring external signal converters. System integrators utilize this primary control hub for decentralized, stand-alone equipment automation, relying on its replaceable internal lithium battery to preserve historical trend logs and real-time clock functions. Furthermore, the controller includes a built-in expansion port and a dedicated Smart Sensor interface, allowing facility managers to seamlessly scale point capacity and facilitate localized temperature adjustments as mechanical requirements evolve.
Key Features:
● Native BACnet MS/TP: Communicates seamlessly as a Master device on RS-485 networks, ensuring strict interoperability with third-party BACnet facility systems.
● High-Density I/O: Features 16 universal inputs, 8 Form C relay outputs, and 8 analog outputs to directly manage high-capacity commercial mechanical plants.
● Flash Memory Reliability: Utilizes non-volatile memory to securely store both the operating system and user applications, protecting programming data without ROM swaps.
● Rapid 32-Bit Processing: Incorporates a Motorola Coldfire microprocessor to execute complex, object-oriented control algorithms with virtually no computational delay.
● Output Overrides: Equips each output with a manual override switch, providing technicians with direct physical control during routine maintenance or network disruptions.
● Smart Sensor Integration: Provides a dedicated connection port for an Andover Continuum Smart Sensor to enable localized setpoint adjustments and occupancy monitoring.
● On-Board Battery Backup: Protects critical runtime parameters and historical data logs during sudden electrical failures utilizing a replaceable lithium battery.
The B3920 delivers the reliability and digital precision required for centralized equipment automation and seamless network integration in demanding building management systems.
