Ordering Information 

For spares, order the complete catalog number as 
described below.  This includes a front panel 
assembly, monitor PWAs with sheet metal, and 
appropriate relay module.  This unit is optioned, 
tested and ready to install in your system.  Spare 
relay modules can be ordered separately.
