2.1.2 ORDERING
The relay is available as a 19-inch rack horizontal mount unit or a reduced size (¾) vertical mount unit, and consists of the
following modules: power supply, CPU, CT/VT, digital input/output, transducer input/output. 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).
The L60 can be ordered either with one Type 8P CT/VT module or with two CT/VT modules (8P plus 8F). The L60 is
ordered with one CT/VT module for applications where one set of three-phase line currents is supplied to the relay. Voltage
based functions are not available on units with one CT/VT module. When the L60 is ordered with 2 CT/VT modules, two
sets of three-phase currents from two CTs can be individually fed into the relay. Voltage based functions (such as distance,
undervoltage, synchrocheck, etc.) are available on units with two CT/VT modules.
