Digital I/O Conversion Module
(Cat 1492-CM1771-LD013)
I. Description
This Digital I/O Conversion Module provides for the conversion of (1) 1771, 32 point I/O modules to be converted
to (2) 1756, 16 point I/O module and consists of the following:
(1) 1771 Module (32pt) to (2) 1756 Modules (16pt)
(1) Conversion Module: 1492-CM1771-LD013
(1) Cable: 1492-CONCAB005S3 or 1492- CONCAB005S4 (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 are (2) Removable Terminal
Blocks (RTBs) for the (2) 1756 I/O modules, 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 (2) 1756 I/O modules per
the Wiring Diagrams in Section V. As standard, the 1492 Cables are 0.5M long, but we also offer a 1.0M cable
length. Refer to the footnotes in Table 2 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.

oot 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.

Conversion Module Installation and Application Considerations
This Bul. 1492 cable consists of a cable wired to two 1756-OA16 RTB. Recommended cable lengths of 0.5M or 1.0M (005=0.5M,
010=1.0M). See table 2 for other lengths.
The 1771-OAN module output current limits versus 1756-OA16 limits are as follows:
1771-OAN 1756-OA16 w/ 1492-CONCAB005S3
a) Current/Point 1A 0.5A
b) Current/Module 8A (32 pts) 2A (16 pts)
c) Surge Current/Point 10A for 25ms 5A for 43ms
The 1771-OAN has 4 groups (allowing 4 separate power supplies). This module/cable combination ties all 4 groups from the 1771-OAN
together. Field wiring modification must be made to accommodate this if mulitple supplies were used. If more than 1 supply was used, all but
1 of the power supplies must be removed.
The 1771-OAN did not allow connections for L2, however the 1756-OA16 requires an L2 connection for proper operation. The 1771-OAN
did not use terminals 10, 20, 30, 40. These terminals have been reassigned for an L2 connection in this application. The installer must
rewire L2 to one of these terminals.
Refer to your 1771-OAN and 1756-OA16 Installation Manual wiring schematics and diagrams for more details. Ensure 1756 output
module ratings are not exceeded.
This configuration uses two (2) 1756-OA16 output modules to replace a single 1771-OAN output module. This may require the use of a
larger 1756 I/O chassis and conversion mounting assembly. Ensure there is sufficient panel space to allow for this possibility.

The 1771-OWNA has 4 groups (allowing 4 separate power supplies). This module/cable combination ties all 4 groups from the 1771-OWNA
together. Field wiring modification must be made to accommodate this if mulitple supplies were used. If more than 1 supply was used, all but
1 of the power supplies must be removed.
The 1771-OWNA did not allow connections for L2, however the 1756-OW16I requires an L2 connection for proper operation. The 1771-OWNA
did not use terminals 10, 20, 30, 40. These terminals have been reassigned for an L2 connection in this application. The installer must rewire L2 to
one of these terminals.
Refer to your 1771-OWNA and 1756-OW16I Installation Manual wiring schematics and diagrams for more details. Ensure 1756 output module
ratings are not exceeded.
This configuration uses two (2) 1756-OW16I output modules to replace a single 1771-OWNA output module. This may require the use of a
larger 1756 I/O chassis and conversion mounting assembly. Ensure there is sufficient panel space to allow for this possibility.
1756-OW16I output modules has all inputs jumpered together pins 2 through 34 even.
