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. Table 1: Bulletin 1771 to 1756 Chassis Conversion 1771 Chassis Cat.

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.
