GENERAL
The XFL521B, 522B, 523B, and 524B modules are LONMARK
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
ONWORKS standard network
variables (SNVTs). Each Distributed I/O module plugs into a
base terminal block allowing communication with controllers
via the built-in Echelon
®
LONWORKS 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 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.
DESCRIPTION
These Distributed I/O modules use a Neuron® chip and an
FTT-10A free topology transceiver for communication on a
L
ONWORKS bus and comply with LONMARK Application Layer
Guidelines V3.2.
