HOW THe UNIVeRSAL INPUT mODULe WORKS

The Universal Input Module provides eight inputs that can be configured for use with a vari-

ety of sensors. Each input has a configuration jumper that conditions the signal appropriately

based on the attached sensor. The module continuously reads the signal at each input and

communicates the value back to the SCADA 3000 via the 4-wire communications bus. The

SCADA 3000 will allow you to set customized tables to scale the input accordingly. The value

of each input can be used in the ladder program or C-program to perform control functions.

You may even choose just to monitor or datalog an input and activate alarms based on high and

low set-points. The SCADA 3000 User’s Manual provides information on how to take advan-

tage of all the possibilities. Listed below are some of the possible applications for the Universal

Input Module:

Temperature
Humidity
Power (Voltage level, Current level, Power consumption)
Pressure
Liquid Level
Refrigerant Leak Detector
Water Detector
Weather (wind speed, wind direction, barometric pressure, rainfall)
Vibration

Sensors to monitor just about any condition are available. See the Accessories listing in

Appendix G of the main unit User’s Manual or contact Phonetics for more information.
