2. Demand Response Unit (DRU)
Reason for change
153 MHz signal is being narrow banded
MVEC at the controls (managing the control process)
Final piece of the AMI (smart meter) puzzle
$ lost on control strategy

3. DRU (cont.) Difference Controlled by PLC
No orange and blue wires now port 0 port 1
We would like to see wires identified on romex jacket or tagged.
No easy means of bypass
No means of testing

4. DRU (options) LED lights
Top light (240ac supply) illuminated green when voltage is applied
Middle light is DRU fault red when low voltage or low frequency is applied
Bottom light “demand” control strategy is issued when amber in color

5. Relay 30/5 amp Two relays with single contact “NC”
Adjustable coil on 5 amp
Pin connector
Certain models
Can be used as test area
No way to alter or change relay’s
24V limitation on 5A

6. Relay 30/30A Standard Contacts 2 relays NC No voltage limitations
Black relays used for multiple loads

7. New 12 vdc supply 240 vac input 12 vdc output
Used for coil voltage with ice cube relay’s
30/5A relays
Need to change jumper
De-energized coil
30/30A relays
Multiple relays
Retrofit
