Excel 50
CONTROLLER
HONEYWELL EXCEL 5000 OPEN SYSTEM
SPECIFICATION DATA
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 LonWorks® network communicating
with Excel 10 controllers as room/zone controllers or with 3
rd
-
party products. It can also serve as a standalone 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 Vari-
ables according to the LonMark Interoperability Guidelines
V.3.0. It can serve 22 integrated I/Os and supports peer-to-
peer communication; thus, in the case of larger-scale ap-
plications, several different controllers can be linked and
accessed. The system firmware is stored in EPROM or 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 available either as a
• configurable controller with a separate application
module for each group of applications (XD50FL-AH03-EN,
XD50FCL-HT02-GE, etc.). In this case, a specific applica-
tion is chosen using the Lizard® application selector and
then entered as a code number via the MMI or an external
interface. The number of LONMARK NVs (typically about
60) is determined by the chosen application; or as a
• freely programmable controller with an application
module, engineered using Honeywell's CARE
programming tool, and a maximum of 46 LONMARK NVs.
FEATURES
• Various state-of-the-art communication options: Open
LONWORKS® bus or C-bus communication; modem or
ISDN terminal adapter at up to 38.4 Kbaud; wireless com-
munication via GSM; dial-up through TCP/IP networks
• Unique features in open LONWORKS® networks: NV-
Booster® reduces the number of required NVs and thus
also the number of required controllers; NV bindings can
be restored after controller reset (and thus need not be
redone after exchanging controllers); 46 NVs supported
for LONWORKS integration
• Reduced engineering and start-up costs: Huge variety
of pre-tested and fully documented applications, con-
figured with the PC-based Lizard application selector
• Easy and flexible installation: Screw terminals;
mounting inside cabinet (DIN rail) or in cabinet front door
• Hardware / software options: With or without: XI582AH
operator interface; Excel Online (formerly XI584) operator
and service software; MMI (for buswide access to other
controllers)
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 XI582AH operator interface or the PC-based XI584
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 con-
troller 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 Excel 50 is available in two standalone versions (with or
without EPROM) or with different application modules and
bus interfaces (see Table 1). Large RAMs provide for in-
creased trending capability. A modem or ISDN terminal
adapter can be connected to the serial port of all models
equipped with Flash EPROM to allow remote access at up to
38.4 Kbaud. Connection to a Siemens M20 terminal permits
wireless communication via GSM.
All changeable parts or switches are accessible without
opening the housing. Communication capabilities and
memory are easily upgraded by replacing application
modules.
