VI. Appendix A - 800 Housing to 1756 Chassis Conversion System Selection Process
1) Determine the number of 800 I/O modules actually used in the 800 I/O Housing to be converted to 1756.
2) Review the data in Column 5 from the below table, and select a 1756 I/O Chassis which meets your conversion
needs from Step 1. Ensure the information from the I/O Conversion module table is reviewed first since in some
cases, two 1756 modules are needed to replace one 800 I/O module.
3) Once the 1756 Chassis is selected, refer to Column 7 and select the Conversion Assembly.
One chassis slot required for the ControlLogix processor or a remote I/O adapter type module.
The footprint and mounting dimensions of the 1492 Conversion Assembly (base plate and cover plate) match those of the
Modicon I/O Housing.
Width dimension includes the 1756 Chassis power supply.
Surplus Chassis width as compared to the 800 I/O Housing is divided equally when mounting it on the Conversion Assembly.
Mounting holes for the 1756 I/O Chassis are pre-drilled and pre-tapped into the Conversion Assembly cover plate.
