8 inputs
Each input (1 to 8) can be used as a discrete, analog, or
temperature input
Discrete inputs can be dry contact or pulsed dry contact
Analog inputs can be 4 to 20 mA or 0 to 10 vdc
Temperature inputs can be 5K or 10K ohm thermistors
8 outputs
Each output (1 to 8) can be discrete or analog
Discrete outputs are 24 vdc at 80 mA
Analog outputs are 4 to 20 mA or 0 to 10 vdc (varies
with point type)
Carrier network features
When included in a network with other network control-
lers, Option Modules, and user interfaces, the following
additional capabilities are possible:
Alarm processing, messages, and annunciation
Runtime, history, and consumable data collection and
report generation
Demand limiting
Broadcast of data such as outside-air temperature, out-
side air humidity, and time of day
Timed overrides for use with Tenant Billing
•Airside linkage
Enclosure and power supply
The Universal Controller is designed so that it can be easily
installed in a field-supplied enclosure (not outdoor rated).
The Universal Controller uses any standard, Class II, SELV-
compatible, field-supplied 24 vac, 60 va transformer.
