Product Description

The Excel Web II model XL2000B3A is Honeywell's Ethernet-based, freely programmable Building Automation controller that provides network security, universal operation and reduces total installation cost for building investors and building operators; it offers a combination of BACnet IP, BACnet MS/TP, and LONWORKS communication, enabling control over a huge variety of building management applications such as traditional heating, ventilation, and air conditioning (HVAC) applications, energy management functions (including optimum start/stop, night purge, and maximum load demand), as well as supervisory functions for lighting, sun-blind, heat and energy metering and many others. Boasting features and benefits like reduced total installed cost, universal operation, lower service, operation and maintenance costs, fast application control, reliable control performance, embedded e-mail/SMS alarming, and flexible mounting options, this controller is also certified to DIN EN ISO 16484-5.
Specification Item Details
Communication Protocols Supports BACnet IP, BACnet MS/TP, and LONWORKS communication, and also supports Modbus RTU master and M-bus (EN 1434-3).
Control Functions Can be used for a variety of building management applications, including traditional HVAC applications, energy management functions (such as optimum start/stop, night purge, and maximum load demand), and supervisory functions for lighting, sun-blind, heat, and energy metering.
Operation Mode An integrated web server allows local and remote operation through standard browsers.
Network Security When operating in IP networks, private networks (such as VPN) must be used, or protection against the open internet (such as with external firewalls) must be ensured.
Cost-Saving Features Uses the existing standard Ethernet/LAN infrastructure for communication, and the flexible and optional use of onboard I/Os and panel bus I/Os further reduces costs.
Technical Features Four selectable control loop priorities (multitasking), selectable control loop cycle times, and event-driven switching tables; can record the trend of 100 data points.
Mounting Method Suitable for mounting in cabinets, in fuse boxes conforming to DIN 43880 (with a maximum slot height of 4), and can also be vertically mounted on DIN rails.
Protection Level IP20 when mounted on the wall with two accessory MVC-80-AC covers; IP30 when mounted on the cabinet door with the accessory MVC-80-AC 2.
