Figure 3–29: DIRECT INPUT AND OUTPUT SINGLE/DUAL CHANNEL COMBINATION CONNECTION
The interconnection requirements are described in further detail in this section for each specific variation of type 7 commu-
nications module. These modules are listed in the following table. All fiber modules use ST type connectors.
Not all the direct input and output communications modules may be applicable to the D60 relay. Only the modules
specified in the order codes are available as direct input and output communications modules.
