Configuring Terminal Modules
The E1460A 64-Channel Relay Multiplexer consists of a relay switch card
and a (standard) screw-type terminal module or a crimp-and-insert terminal
module (Option A3E). See Figure 1-10 for the multiplexer’s connector
pin-out that mates to the terminal module.
Standard Terminal
Module Description
Figure 1-8 shows the standard screw-type terminal module connectors and
associated bank numbers, channel numbers, and line designations. Use the
following guidelines for wiring connections:
• Be sure that wires make good connections on screw terminals.
• Maximum terminal wire size is No. 16 AWG. When wiring all
64-channels, a smaller gauge wire (20-22 AWG) is
recommended.
• Wire ends should be stripped 6mm (0.25 in.) and tinned to 
prevent single strands from shorting to adjacent terminals.
Terminal Module
Option A3E
Description
Terminal module Option A3E (see Figure 1-9) provides a crimp-and-insert
terminal module that allows you to crimp connectors onto wires which are
then inserted directly into the multiplexer’s mating connector. See the
pin-out diagram (Figure 1-10) to make the connections. Table 1-3 shows the
accessories that can be used with crimp-and-insert Option A3E.
