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.

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.

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.
For Sinking applications use 1492-CM1771-LD007. [Reference Doc: 41170-991 (Version 00)]

Conversion Module Installation and Application Considerations
This Bul. 1492 cable consists of a cable wired to one 1756-OA8E RTB. Recommended cable lengths of 0.5M or 1.0M (005=0.5M,
010=1.0M). See table 2 for other lengths.
The 1771-OA module output current limits versus 1756-OA8E limits are as follows:
1771-OA 1756-OA8E w/ 1492-CONCAB005U
a) Current/Point 1.5A 2A
b) Current/Module 6A 4A @ 60°C
c) Surge Current/Pt 4A for 8.3ms 20A for 43 ms
The 1771-OA has eight (8) 2A, 250V fuses - 1 per output. The 1756-OA8E is electronically fused per point. Refer to the 1756-
OA8E Installation Manual for details on electronic fusing.
Refer to your 1771-OA and 1756-OA8E Installation Manual wiring schematics and diagrams for more details. Ensure 1756 output
module ratings are not exceeded. [Reference Doc: 41170-943 (Version 01)]

Conversion Module Installation and Application Considerations
This Bul. 1492 cable consists of 2 separate cables (cable “A” and cable “B”) wired to one 1756-OB16D 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 1771-OB module output current limits versus 1756-OB16D limits are as follows:
1771-OB 1756-OB16D w/ 1492-C005005XF
a) Current/Point 1.5A 2A
b) Current/Module 6A 4A @ 60°C
c) Surge Current/Point 4A for 8.3ms 4A for 10ms
The 1771-OB has eight (8) 2A, 250V fuses - 1 per output. The 1756-OB16D is a DIAGNOSTIC MODULE. Refer to the 1756-OB16D
Installation Manual for details on diagnostics.
Refer to your 1771-OB and 1756-OB16D Installation Manual wiring schematics and diagrams for more details. Ensure 1756 output
module ratings are not exceeded. [Reference Doc: 41170-988 (Version 00)]
