HONEYWELL EXCEL 5000 OPEN SYSTEM

FEATURES

 Various state-of-the-art communication options: Open

 Unique features in open L

 Reduced engineering and start-up costs: Huge variety

 Easy and flexible installation: Screw terminals; mounting

 Operating options: Integrated operator interface, XI582

GENERAL

The Excel 50 controller has built-in communication capability, allowing it to be integrated into a Honeywell EXCEL 5000® System or into an open L with Excel 10 controllers as room/zone controllers or with 3 party products. It can also serve as a stand-alone controller. Typical areas of application include heating systems, district heating systems, and air conditioning plants for restaurants, shops, offices, and small branch government buildings.

The Excel 50 supports standard LonMark™ Network Variables according to the LonMark™ Interoperability Guidelines V.3.0. It can serve 22 integrated I/Os and supports peer-topeer communication; thus, in the case of larger-scale applications, several different controllers can be linked and accessed. The system firmware is stored in Flash EPROM located in the application module (a separate module plugged into the controller housing.) Flash EPROM allows easy upgrading of the operating system via download.

The Excel 50 is a freely programmable controller engineered using Honeywell’s CARE programming tool. For L interoperability, a maximum of 46 LonMark™ NVs are available.

DESCRIPTION

The Excel 50 controller is available in two housing versions, one with and one without a Man-Machine-Interface (MMI.) The MMI version allows buswide access to other controllers. The XI582 operator interface or the PC-based XL-Online

operator and service software can be used in conjunction with

either version. The housing can be mounted inside a cabinet

on a DIN-rail or in a cabinet front door.

The Excel 50 has eight analog inputs, four analog outputs, four digital inputs (three of which can be used as totalizers,) and six digital outputs. The digital outputs allow the direct drive of 3-position actuators (up to the max. load.) The controller can be wired either with screw terminal blocks directly at the housing.) Pre-wiring is possible in both cases, and a controller can be replaced without rewiring.

The application modules – all with Flash EPROM – are available in five bus-wide access versions and one standalone version. They feature a variety of bus interfaces (see Table 1.) Large RAMs provide for increased trending capability.

All changeable parts or switches are accessible without opening the housing. Communication capabilities and memory are easily upgraded by replacing application modules.
