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 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.
When using CARE, the Distributed I/O modules 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.
