b3867 Terminal Controllers

The Andover ContinuumTM b3867 is a native BACnet controller that communicates on an RS-485 ﬁeld bus as a Master device using the MS/TP BACnet protocol.

BACnet b3867 Terminal Controllers Features

The b3867 provides cost-effective DDC control of package units, heat pumps, unit ventilators, and other terminal unit applications. Its versatile mix of I/O — Universal inputs, Triac outputs, plus an interface to Andover’s Continuum Smart Sensor room temperature sensor with programmable keypad — allows for ﬂ exible control solutions. The b3867 also features two analog outputs to control reheat valves, dampers, lighting ballasts, etc. And because the b3867 is enclosed in a sleek, modular

The b3867 features Flash memory, increased user memory, and a fast (32-bit) processor for faster scan times, with plenty of additional memory available for data logging of your critical data.

As a native BACnet controller, the b3867 can communicate with other BACnet devices on the MS/ TP network, in strict accordance with ANSI/ASHRAE standard 135-2004, and are listed with the BACnet Testing Labs (BTL) as BACnet Advanced Application Controllers. (B-AAC). By connection to the Andover Continuum b4920 or bCX1 controller, the b3867’s and other MS/TP devices can share and gather data from the wider Ethernet/IP network of controllers. Among those Ethernet controllers can be Andover Continuum controllers (BACnet or Andover Continuum Inﬁ net) or third-party BACnet/IP devices. All Andover Continuum devices, both BACnet and Andover Continuum Inﬁ net, are fully compatible with the Andover Continuum CyberStation front-end software, a fully native BACnet Operator Workstation (B-OWS) application.

Increased Reliability with Flash Memory

The b3867’s non-volatile Flash memory stores your operating system and application programs, so that in the event of a power loss, your application will be restored when power is returned. In additon, the Flash memory allows for easy upgrades of your operating system via software downloads, eliminating the need to swap out proms. The b3867 includes an on-board battery to safeguard your runtime data — protecting all point data and log data from being lost if power is removed.
