The Controller Board is a Neuron-based platform that
executes a zone-level application and allows
communication to all LonMark devices. The
controllers are shipped with pre-loaded applications,
reducing engineering start-up time.
Room Sensor
Room SensorRoom Sensor
Room Sensor
The room sensor connection to the controller board
consists of a quick-connect RJ-11 jack. This
streamlines the installation and reduces the LTEC
Controller's start-up time.
Spare Input/Output Points
Spare Input/Output PointsSpare Input/Output Points
Spare Input/Output Points
The LTEC Controller, depending upon the application
used, may have up to 3 input and 2 output spare
points available. These points can be used to perform
local connection and network control for devices
located in close proximity to the LTEC Controller,
therefore reducing costs associated with installation.
The controller board is available in either 4 IN / 6 DO or
5 IN / 8 DO / 3 AO styles.
