Keying

The I/O chassis can be physically keyed to prevent accidental
damage caused by inserting a module into a slot wired for a
different module type. Figure 11 illustrates how the slot keys
are installed on the I/O chassis slot field wiring connectors.
The slot key positions for the thermocouple input module is
listed in Table 3.
