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