Digital I/O Conversion Module
(Cat 1492-CM1771-LD010F)
I. Module
This Digital I/O Conversion Module provides for the conversion of (1) 1771, 16 point I/O modules to be converted to
(1) 1756, 16 point I/O module and consists of the following:
(1) 1771 Module (16pt) to (1) 1756 Module (16pt)
(2) Conversion Module: 1492-CM1771-LD010F
(1) Cable: 1492-CONCAB005Y (Table 2)
(1) Conversion Mounting Assembly: 1492-MUA… (Table 1)
This conversion is accomplished without the removal of any field wires from the existing 1771 Swing Arm. The existing 1771 Swing Arm fits directly onto the edge connector of the 1492 Conversion Module. On one end of the 1492
Cable is (1) connector for the Conversion Module. On the other end is the Removable Terminal Block (RTB) for the
1756 I/O module, as shown in the photo below. The I/O signals are routed through the 1492 Conversion Module and
the 1492 Cable to the appropriate terminals on the 1756 I/O module per the Wiring Diagrams in Section VI. As standard, both portions of the 1492 Cables are 0.5M long, but we also offer a 1.0M cable length. Refer to the footnotes
in Table 2, Section III for further details.

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. Installation
The 1492 Conversion Modules must be installed in a 1492 Conversion Mounting Assembly (see Table 1 below). A
complete System Installation Manual ships with the 1492 Conversion Mounting Assembly.
1) Determine the quantity of each type of 1771 I/O modules used in the 1771 I/O Chassis to be converted.
2) Select the applicable 1492 Conversion Modules from Table 2, Section III.
3) Review the Max Slots for I/O and Chassis Width data from the Table 1 below.
4) Select a 1756 I/O Chassis which has enough I/O Slots.
NOTE: (2) I/O slots are required in the 1756 Chassis for conversions where (1) 1771 I/O module converts to (2) 1756 I/O
modules.
5) Select the 1492 Conversion Mounting Assembly which has enough Conversion Module slots.
NOTE: (2) Conversion Module slots are required in the 1492 Conversion Mounting Assembly for conversions where (2)
1771 I/O module convert to (1) 1756 I/O modules.
NOTE: The 1492 Conversion Mounting Assembly has the same Height & Width foot-print as the 1771 Chassis and is
designed to use the same mounting hardware. The combined Depth of the 1492 Conversion Mounting Assembly with the
1756 Chassis mounted on top is 10.25 inches (Controller w/key) or 10.0 inches (Controller w/o key). Dimension drawings
are included in the System Installation Manual that ships with the 1492 Conversion Mounting Assembly.

t Notes:
1771-A3B is not listed as it is used for 19 inch wide instrumentation panels.
Notice that the 1756 Chassis Width sometimes exceeds the 1771 Chassis Width, with or without the Power Supply. The
Cover-Plate of the 1492 Conversion Mounting Assembly allows the 1756 Chassis to be Left justified, Right justified or
Centered. A complete System Installation Manual ships with the 1492 Conversion Mounting Assembly.
