5.4 Signal Cable Connection to Digital Input/

Output Modules

This section contains wire connection diagrams and tables with the I/O channel numbers.

There are three ways of connecting input signal cables to digital I/O modules: by connecting

via a pressure clamp terminal block, by using a signal cable to connect to the connectors via

a terminal board, or by direct connection using a MIL cable.

The following table shows the relationship between the digital input/output module and the

field wiring connection methods.
