Digital I/O Conversion Module

(Cat 1492-CM1771-LD014)

I. Description

This Digital I/O Conversion system provides for the conversion of (1) 1771, 8 point I/O module to (1) 1756, 8 point I/O module OR (2) 1771, 8 point I/O modules to (1) 1756, 16 point I/O module and consists of the following:

(1) 1771 Module (8pt) to (1) 1756 Module (8pt)

(1) Conversion Modules: 1492-CM1771-LD014 (1) Cable: 1492-CONCAB005U, 1492-CONCAB005V, 1492-CONCAB005W (Table 2) (1) Conversion Mounting Assembly: 1492-MUA… (Table 1)

(2) 1771 Module (8pt) to (1) 1756 Module (16pt)

(2) Conversion Modules: 1492-CM1771-LD014 (1) Cable: 1492-C005005X_ (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 Arms fit directly onto the edge connectors of the 1492 Conversion Modules. On one end of the 1492 Cables are (1) or (2) connectors for the Conversion Modules. 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 IV. 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, Section III for further details.

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.

t 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 2 separate cables (cable “A” and cable “B”) wired to one 1756-IB16I RTB. Each cable can be either 0.5M

or 1.0M (005=0.5M, 010=1.0M). Ensure that cable A and cable B are connected to the correct module in the conversion.



The input delay times for the 1771-IQ module versus the 1756-IB16 module are as follows:

1771-IQ 1756-IB16I w/1492-C005005XJ a) Off-to-On Delay 12ms (+/-14ms) 1ms max (plus selectable filter) b) On-to-Off Delay 12ms (+/-14ms) 4ms max (plus selectable filter)

 The 1771-IQ module is rated 5V to 30V DC. The 1756-IB16I module is rated 10V to 30V SOURCING DC only.  Refer to your 1771-IQ and 1756-IB16I Installation Manual wiring schematics and diagrams for more details.
