Allen-Bradley 1492 Field Conversion Module Installation Instructions

Digital I/O Conversion Module
(Cat 1492-CM1771-LD004)
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 and consists of the following:
(1) 1771 Module (16pt) to (1) 1756 Module (16pt)
(2) Conversion Module: 1492-CM1771-LD004
(1) Cable: 1492-CONCAB005Y (Table 2, Section III)
(1) Conversion Mounting Assembly: 1492-MUA… (Table 1, Section II)
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 V. 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.

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.

The input delay times for the 1771-ID16 module versus 1756-IA16I module are as follows:
1771-ID16
1756-IA16I
a) Off-to-On Delay
0.57ms
10ms max (plus selectable filter)
b) On-to-Off Delay
9ms or 18ms (selectable)
8ms max (plus selectable filter)
The 1771-ID16 module is rated 74V to 138V AC and105V to 138V DC. The 1756-IA16I is rated 79V to 132V AC. If the input
source voltage is DC use a 1756-IH16I with this conversion module.
