Steps To Determine Power Needed; I/O Modules' Factory Settings And Va Ratings - Electro Industries 1252 Installation And Operation Manual

5.12: Steps to Determine Power Needed

•
Available power for All Ports of the Nexus 1250/1252 is 12 VA.
•
Refer to the table below to determine the VA Ratings for I/O modules and displays.
•
Add together the VA Ratings for I/Os and Displays in use.
•
Compare Available Power to Power Needed to determine if you must use an additional
power source. EIG recommends the PSIO 12V power source. See section 9.2.1.

5.13: I/O Modules' Factory Settings and VA Ratings

All I/Os are shipped pre-programmed with a baud rate of 57600 and addresses. The table below
details the factory-set address for each module and the VA Ratings for I/O modules and Nexus
displays. Refer to the previous section (section 5.12) for the steps to determine if you must use an
additional power source. For programming, refer to Chapter 8 of the Communicator EXT User
Manual.
