The XFL521B, 522B, 523B, and 524B modules are L
compliant digital and analog I/O modules which can be
installed at strategic locations within a building. These
modules convert sensor readings and provide output signals
used for operating actuators via L
variables (SNVTs). Each Distributed I/O module plugs into a
base terminal block allowing communication with controllers
via the built-in Echelon
minal block provides spring clamp terminals for easy connec-
tion of field cables from the various sensors and actuators.
The modular system allows DI/O's to be removed from the
system without disturbing other modules. The module with
terminal block mounts easily onto a DIN rail.
When using CARE, the DI/O's can be automatically bound
and commissioned to the Excel 500 CPU (XC5010C,
XC5210C, XCL5010) and XL50. When the modules are used
by other controllers, provided plug-ins permit the modules to
be commissioned by CARE 4.0 or by any LNS network
management tool.

Distributed I/O
 L
™ compliant
 2-wire L
bus interface between controller
and I/O
 No additional field terminals required
 Usable with Excel 500 controllers in conjunction with
standard internal I/O modules
 Automatic binding and commissioning to Excel 500
controllers when using CARE
 Connector module with sliding bus connector
(eliminating the need to wire together neighboring
 Fast connection due to spring clamp terminals
 Module exchange during operation
 Alarm in case of defective module
 Mechanical coding prevents mismatching of modules
 Power LED (L1, green) and L
red) on all electronics modules
 Status LEDs for outputs and digital inputs
 Optional manual override modules for analog and
digital output modules with feedback
 XILON for wiring test
These Distributed I/O modules use a Neuron® chip and an
FTT-10A free topology transceiver for communication on a
bus and comply with L
Guidelines V3.2.
