GENERAL
The XFL521B, 522B, 523B, and 524B modules are L
ON
M
ARK
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
ON
W
ORKS
standard network
variables (SNVTs). Each Distributed I/O module plugs into a
base terminal block allowing communication with controllers
via the built-in Echelon
®
L

ORKS
bus interface. The ter-
minal block provides spring clamp terminals for easy connec-
tion of field cables from the various sensors and actuators.
The modular system allows Distributed I/O modules to be
removed from the system without disturbing other modules.
The module with terminal block mounts easily onto a DIN-rail.
The Excel 500 CPU (XC5010C, XC5210C, XCL5010) is
capable of automatically binding and commissioning the Dis-
tributed I/O modules via the L

bus. When the
modules are used by other controllers, plug-ins are provided
so that the modules can be commissioned by any LNS or
non-LNS installation or network management tool.
DESCRIPTION
The XFL521B, 522B, 523B, and 524B are Distributed I/O
modules that use a Neuron® chip and an FTT-10A free
topology transceiver for communication on a L
ON

ORKS
bus.
The modules are compliant with L
