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
rd
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.

XL50A-MMI and XL50A-CY (with Man-Machine Interface);
XL50A (without MMI.)
Versions with MMI
Both the XL50A-MMI and the XL50A-CY feature a keypad
(with eight function keys and four fast-access keys) and an
LCD display.
The LCD display of the XL50A-MMI has four lines, 16
characters per line, adjustable contrast, and backlight.
The LCD display of the XL50A-CY features 128 X 64 dot
graphics, adjustable contrast, and backlight.
Application Modules
The Excel 50 controller can be upgraded by direct firmware
download via serial port or C-Bus. Contact your local
Honeywell affiliate for more information on the available
firmware and applications.
