2.1.2 ORDERING
a) OVERVIEW
The D30 is available as a 19-inch rack horizontal mount or reduced-size (¾) vertical unit and consists of the following mod-
ules: power supply, CPU, CT/VT, digital input and output, transducer input and output, and inter-relay communications.
Each of these modules can be supplied in a number of configurations specified at the time of ordering. The information
required to completely specify the relay is provided in the following tables (see chapter 3 for full details of relay modules).
Order codes are subject to change without notice. See the GE Multilin ordering page at
http://www.gedigitalenergy.com/multilin/order.htm for the latest ordering options.
The order code structure is dependent on the mounting option (horizontal or vertical) and the type of CT/VT modules (regu-
lar CT/VT modules or the HardFiber
TM
modules). The order code options are described in the following sub-sections.
