SEL-311C Relay Instruction Manual Date Code 20060320
Introduction & Specifications
SEL-311C Models
SEL-311C Models
This instruction manual covers the SEL-311C models listed in Table 1.1.
The model numbers are derived from the SEL-311C ordering information
sheet. The model numbers in Table 1.1 are only the first part of an actual
ordering number—enough to distinguish one model type from another. The x
field indicates horizontal, vertical, rack, or panel mounting. These numbers
should not be used to order an SEL-311C. To order an SEL-311C, refer to the
actual ordering information sheets.
Model 0311C00x and 0311C01x differ only in that model 0311C01x is
available with an extra I/O board (and thus increased rack unit height—see
Figure 2.1).
A vertical SEL-311C is available in both 0311C00x and 0311C01x models.
The vertical relays use the same rear panels as the horizontal models in
Figure 2.2, Figure 2.3, and Figure 2.8 through Figure 2.11.
Throughout this instruction manual, when differences among the SEL-311C
models in Table 1.1 are explained, model numbers are referenced for clarity.
Differences between models 0311C00x and 0311C01x appear in references to
optoisolated inputs, output contacts, and board jumpers. Figure 2.16 and
Figure 2.17 and Table 2.2 through Table 2.4 show the labeling differences
between the board jumpers.
