5.3.11: Steps to Determine Power Needed
•
The Nexus® 1262/1272 meter's Power Supply DOES NOT SUPPLY POWER to the
Output Modules.
•
Refer to the table in the next section (Section 5.3.11) to determine the VA Ratings for Output
modules and displays.
•
Add together the VA Ratings for Output modules and displays in use to determine power
needed.
•
Connect one or more PSIO units. (PSIO is designed for use with the Output modules.)
Each PSIO will supply 12 VA @ 12V dc . For details on PSIO, see Section 10.2.1.
NOTE: For 24 or 48 V dc applications, EIG recommends the PB1 (or PSIO) power supply.
Order example number: PB1-D2-12VO (or PSIO-D2). See Figure 5.11 for wiring.
5.3.12: Output Modules' Factory Settings and VA Ratings
All Output modules are shipped pre-programmed with a baud rate of 57600 and individual address-
es. The table below details the factory-set address for each module and the VA Ratings for Output
modules and displays. Refer to the previous section (Section 5.3.11) for the steps to determine the
power required. For programming details, refer to the accompanying Communicator EXT User
Manual.
