I. Module Description
The 1492-CM1771-LD004 conversion module provides field wire signal conversion from an A-B 1771-ID16, 74 to
138Vac or 105 to 138Vdc, 16 point individually isolated input module to a 1756-IA16I, 79 to 132Vac, 16 point
individually isolated input module or a 1756-IH16I, 90 to 146Vdc, 16 point individually isolated input module. The
1492-CM1771-LD004 conversion module also provides field wire signal conversion from an A-B 1771-IQ16, 10 to
32Vdc, 16 point individually isolated input module to a 1756-IB16I, 10 to 30Vdc, 16 point individually isolated
input module. The conversion module provides the mating connector to the 1771-ID16 or 1771-IQ16 module
swing-arm/terminal block with the attached field wires. It routes those signals via its 37-pin connector and a
1492-CONCABY pre-wired cable to compatible terminals on the 1756-IA16I, 1756-IH16I or 1756-IB16I (refer to
Wiring Diagrams on page 2, 3 and 4 for details).
II. Module Installation
The 1492-CM1771-LD004 conversion module must be installed in a 1492 conversion base-plate and cover-plate
assembly. The installation of the module into the assembly is explained in the Installation Manual that ships with the
conversion assembly. For a list of compatible assemblies refer to Appendix A.

De-energize and lockout any and all power to all I/O field devices connected to the A-B 1771 I/O chassis,
and the power to the 1771 I/O chassis itself. Ensure all power is de-energized and locked out to any
device in the control cabinet where the conversion is to be performed. Ensure work is performed by
qualified personnel.

IV. Conversion Module Wiring Diagram
The following diagrams show the connections from the existing 1771-ID16 and 1771-IQ16 swing-arm, through the
conversion module, 1492 cables and to the 1756-IA16I, 1756-IH16I or 1756-IB16I input module. The diagram can be
used as an aid in possible system troubleshooting.
There are several key application considerations and system specifications (bottom of drawing) when
using these components (conversion module, cable and input module). Read and understand these
considerations before installation.

VI. Appendix A
1771 chassis to 1756 Chassis Conversion System Selection Process
1) Determine the number of 1771 I/O modules used in the 1771 I/O Chassis to be converted to 1756. NOTE: In some
cases two 1756 modules may be required for one 1771 module. Select the applicable 1492 conversion modules from the
Digital and Analog Conversion Selection Table Matrix.
2) Review the Max Slots for I/O and Chassis Width data 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 tables are reviewed first.
3) Once the 1756 Chassis is selected, select the Conversion Assembly. The Conversion Assembly has the same dimen-
sional foot-print as the 1771 chassis and can use the same mounting hardware. The assembly consists of a base-plate
to hold the conversion modules and a cover-plate to protect the modules and to mount the selected 1756 chassis. The
combined depth of the conversion assembly with the 1756 chassis mounted is 10.25 inches (Controller w/key) to
10.0 inches (Controller w/o Key).
Foot Notes:
1771-A3B is not listed as it is used for 19 inch wide instrumentation panels
Two 1771 width dimensions are provided as some PLC-5 processors have integrated power supplies. Dimension w/PS
includes -P1, -P2, etc. Notice that the width dimension of some 1756 chassis exceed the width of the 1771 chassis with
or without the power supply. Cover-plate chassis mounting design allows the excess 1756 chassis width to be evenly
distributed to both sides, or excess to right or left. Carefully consider this in the conversion
1756-A4 may work in a 1771-A1B application if 4 or less I/O slots were used. Conversion cover-plate is capable to
mount -A4 or -A7
1756-A7 may work in a 1771-A2B application if 6 or less I/O slots were used. Conversion cover-plate is capable to
mount -A7 or -A10
1756-A10 may work in a 1771-A3B1 application if 10 or less I/O slots were used. Conversion cover-plate is capable to
mount -A10 or -A13
1756-A13 may work in a 1771-A4B application if 13 or less I/O slots were used. Conversion cover-plate is capable to
