Allen-Bradley 1492 Field Conversion Module Installation Instructions

Digital I/O Conversion Module
(Cat 1492-CM1771-LD006)
I. Description
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 OR (1) 1771, 16 point I/O module to (2) 1756, 8 point I/O modules, and consists of the following:
(1) 1771 Module (16pt) to (1) 1756 Module (16pt)
(1) Conversion Module: 1492-CM1771-LD006
(1) Cable: 1492-CONCAB005X (Table 2)
(1) Conversion Mounting Assembly: 1492-MUA… (Table 1)
(1) 1771 Module (16pt) to (2) 1756 Module (8pt)
(1) Conversion Module: 1492-CM1771-LD006
(1) Cable: 1492-CONCAB005S2 (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 Arms. The existing 1771
Swing Arm fits directly onto the edge connectors of the 1492 Conversion Module. On one end of the 1492 Cable is (1) connector for the Conversion Module. On the other end are (1) or (2) Removable Terminal Blocks (RTBs) for the 1756 I/O module(s),
as shown in the photos 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(s) 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.

Printed in U.S.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.
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.

Foot 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 one 1756-OG16 RTB. Recommended cable lengths of 0.5M or 1.0M
(005=0.5M, 010=1.0M). See table 2 for other lengths.
The 1771-OGD module output current limits versus 1756-OG16 limits are as follows:
a) Current/Point
b) Current/Module
1771-OGD
1mA
310mA
1756-OG16 w/ 1492-CONCAB005X
24mA
384mA
The 1771-OGD has a single 10A, 250V rectifier fuse (1/4 x 1-1/4 inch). The 1756-OG16 is electronically fused per
group. Refer to the 1756-OG16 Installation Manual for details on electronic fusing.
The 1771-OGD is rated 10V to 60V DC. The 1756-OG16 is rated 10V to 31.2V DC.
Refer to your 1771-OGD and 1756-OG16 Installation Manual wiring schematics and diagrams for more details. Ensure
1756 output module ratings are not exceeded.

The 1771-OMD has a single 10A, 250V rectifier fuse (1/4 x 1 1/4 inch). The 1756-OA16 has a mechanical 3.15A @250V AC
slow blow fuse. Refer to the 1756-OA16 Installation Manual for details on electronic fusing.
The 1771-OMD is rated 184V to 250V AC. The 1756-OA16 is rated 74V to 265V AC. If the load source voltage is greater than
30V DC, then use the 1756-OC8 with the 1492-CM1771-LD008F conversion module.
Refer to your 1771-OMD and 1756-OA16 Installation Manual wiring schematics and diagrams for more details. Ensure 1756
output module ratings are not exceeded.

The L2 terminal (Terminal E) on the 1771-ON8 module was an optional connection, but it is required for the 1756-OA16.
This connection must be added if it was not connected.
The 1771-OND is rated 24V AC. The 1756-ON8 is rated 10V to 30V AC.
Refer to your 1771-OND and 1756-ON8 Installation Manual wiring schematics and diagrams for more details. Ensure
1756 output module ratings are not exceeded.
