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.

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.

Foot Notes:

)To understand any issues concerning I/O module compatibility, refer to the Installation Manuals for the specific

1771 and 1756 I/O modules involved.

The 3 numbers indicate the cable length of each portion of the 1492 Cable. Recommended cable length of 0.5M is

shown. Additional cable lengths are as follows:

1.0M = 1492-CONCAB010X or 1492-CONCAB010S2
