B3920 Schneider System Controller BACnet 16 Sensor Inputs 8 Triac Outputs Expansion Bus Port Smart

Product Overview

The B3920 is a BACnet system controller from the Andover Continuum family, designed to operate between field equipment and the head end in building management systems. It features sixteen universal inputs and eight digital or analog outputs, plus a dedicated smart sensor input and expansion port for additional I/O. This configuration enables complete plant room control with a single device that can be expanded later without controller replacement.

The controller's point capacity is commercially significant, determining whether a project requires one panel or multiple units. With sixteen inputs, it can accommodate the typical mix of temperature sensors, status contacts, and flow switches found in small mechanical rooms. As a native BACnet device, it directly exposes objects to the network, supporting interoperability services for reading, trending, alarming, and scheduling without proprietary drivers.

System Integration Notes

This controller level is designed to maintain operation when supervisory layers are unavailable. Control strategies should be written to maintain plant safety and functionality without network dependency.

Point allocation requires careful planning before wiring. While universal inputs are flexible, physical terminal layout must accommodate connected devices. Retrofitting incompatible sensor types is significantly more disruptive than proper initial planning.

When using the expansion port, treat additional I/O as part of the same engineering database rather than separate devices. This maintains consistent point naming and prevents conflicting plant descriptions. Application program backups should be created during commissioning and stored separately from the device.

Application Scenarios

Mechanical Plant Rooms: Controls pumps, valves, temperature sensors, status contacts, and interlocks for commercial building installations
Air Handling Systems: Manages heating/cooling coils, humidifiers, and variable speed drives with individual device monitoring
Infrastructure Maintenance: Used in hospitals, universities, and government facilities maintaining existing Andover Continuum systems
Critical Environments: Applied in data centers and laboratories requiring local logic execution and independent operation
Retrofit Projects: Specified for upgrades where point count and expansion capability allow enclosure and field wiring preservation
