Replaceable Parts List
See the Parts Locator diagram (Figure 3-1) for locations of replaceable parts.
See Table 3-1 for replacement part numbers for the Component Assemblies
and Terminal Modules. A relay multiplexer consists of a Component
Assembly and a Terminal Module.
A Terminal Module consists of a Terminal Card and a Terminal Case
Assembly. For example, to order an E1345A Terminal Module, use
E1345-80001. To order only the Terminal Card, use E1345-66510.
To order only the Terminal Case Assembly, use E1300-84401.
