I. Module Description
The 1492-CM1771-LD002 conversion module provides field wire signal conversion from an A-B 1771-IAD, 79 to
138Vac/dc, 16 point input module to a 1756-IH16I, 90 to 146Vdc, 16 point individually isolated input module or a
1771-IMD, 184 to 250Vac or 166 to 230Vdc, 16 point input module to a 1756-IM16I, 159 to 265Vac, 16 point
individually isolated input module. The conversion module provides the mating connector to the 1771-IAD or
1771-IMD module swing-arm/terminal block with the attached field wires. It routes those signals via its 37-pin
connector and a 1492-CONCABY pre-wired cable to compatible terminals on the 1756-IH16I or 1756-IM16I
(refer to Wiring Diagrams on page 2 and 3 for details).

WARNING
Refer to conversion module Specifications Section: Maximum Operating Voltage
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.
II. Module Installation
The 1492-CM1771-LD002 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.

IV. Conversion Module Wiring Diagram
The following diagrams show the connections from the existing 1771-IAD and 1771-IMD swing-arm, through the conversion module, 1492 cable and to the 1756-IH16I and 1756-IM16I input module. The diagrams can be used as an aid in
possible system troubleshooting.
WARNING

-
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.

Conversion Module Installation and Application Considerations
The input delay times for the 1771-IAD module versus 1756-IH16I module are as follows:
1771-IAD 1756-IH16I
a) Off-to-On Delay 3ms @120V DC 2ms (plus selectable filter)
b) On-to-Off Delay 25ms (+/-5ms) 6ms (plus selectable filter)
The 1771-IAD module is rated 79V to 138V AC or DC. The 1756-IH16I module is rated 90V to 146V DC. If the input
spurce voltage is AC use a 1756-IA16 and 1492-CM1771-LD002 conversion module.
Refer to your 1771-IAD and 1756-IH16I Installation Manual wiring schematics and diagrams for more details.
