(1) To maintain group isolation provided by 32-point I/O modules, use a 1492 terminal block that provides group isolation. 

Consult 1492 documentation or your Allen-Bradley Sales Office for additional information.

(2) Maximum user cable length is dependent on how much voltage drop (current x (ohms/ft.) x (feet)) the user’s system can 

tolerate. The user’s system should take into account the minimum turn-on voltage required by external loads connected to 

the 32-point output modules and all of the voltage drops associated with wiring to and from the load, terminal blocks, 

power sources and the module itself.

Assembly Procedure for Crimp Contacts

The following details the assembly procedure for the crimp type contacts.

1. Strip the wire insulation as shown in Figure 1.

2. Insert the wire up to the wire stop as shown in Figure 2.

3. Crimp with DDK crimp tool 357J-5538. Equivalent Amp part numbers are: 

pin – 87666-2, connector – 102387-9, and crimp tool – 90418-1.

If a crimp tool is not available, used the following crimping procedure:

a. Crimp the wire barrel around the wire using a small needle nose pliers.

b. Crimp the insulation barrel around the wire insulation using a small 

needle nose pliers.

c. Solder wire and wire barrel together.

4. After completing above assembly, insert the cable into the socket housing as 

shown in Figures 3 and 4. Check to make sure that the tang, shown as “A” in 

Figure 4, is properly latched by gently pulling on the wire.
