Analog and Digital I/O Conversion Module(Cat 1492-CM1771-LA004)

I. DescriptionThis I/O Conversion Module provides for the conversion of (1) 1771, 8 Ch Analog I/O module to be converted to (1) or (2) 1756, 6 or 8 Ch Analog I/O module(s) and consists of the following:

(1) Conversion Module: 1492-CM1771-LA004 (1) Cable: 1492-CONACAB005F8 or 1492-CONACAB010F8 (1) Conversion Mounting Assembly: 1492-MUA… (Table 1)

(1) Conversion Module: 1492-CM1771-LA004 (1) Cable: 1492-CONACAB005K8 or 1492-CONACAB005L8 (1) Conversion Mounting Assembly: 1492-MUA… (Table 1)

(1) Conversion Module: 1492-CM1771-LA004 (1) Cable: 1492-CONACAB005F or 1492-CONACAB005K or 1492-CONACAB005L (1) Conversion Mounting Assembly: 1492-MUA… (Table 1)

(1) Conversion Module(s): 1492-CM1771-LA004 (1) Cable: 1492-CONACAB005T1 or 1492-CONACAB005T2 (1) Conversion Mounting Assembly: 1492-MUA… (Table 1)

This I/O Conversion Module also provides for the conversion of (2) 1771 Digital I/O modules that also use the 1771-WF swing arm. In this case, this I/O conversion modules provide for the conversion of (2) 1771, 8 pt. Digital I/O modules to be converted to (1) 1756, 16 pt. Digital I/O module and consists of the following:

(2) 1771 Module (8pt) to (1) 1756 Module (16pt)(2) Conversion Modules: 1492-CM1771-LA004 (1) Cable: 1492-C005005XT (1) Conversion Mounting Assembly: 1492-MUA… (Table 1)

These conversions are accomplished without the removal of any field wires from the existing 1771 Swing Arms. The existing 1771 Swing Arms fit directly onto the edge connector of the 1492 Conversion Modules. On one end of the 1492 Cable are (2) connectors for the Conversion Modules and on the other end is (1) Removable Terminal Block (RTB) for the 1756 I/O module. See the photos below.

The I/O signals are routed through the 1492 Conversion Module(s) and the 1492 Cable(s) 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.

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.

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: 1771-IL(1) to 1756-IF8I (1) (CURRENT)

The 1771-IL input configuration was software configured, as is the 1756-IF8I. Please ensure the correct configuration in the 1756-IF8I.

SHIELD GROUNDING: In some installations, the field wiring shield was grounded on the 1771 chassis. If this was the case, the installer must remove these shield connections from the 1771 chassis and they can be connected to the grounding stud on the 1492-CM1771-LA004 module. The pre-wired cable used between the 1492-CM1771-LA004 module and the 1756-IF8I [1492-CONACAB005K8] provides a shield ground lug to ground the shield at the 1756 ControlLogix chassis, this must be connected. Do NOT connect this ground lug to the conversion module grounding stud.

Refer to your 1771-IL and 1756-IF8I Installation and User Manuals for additional information concerning comparisons of module wiring, features and configuration details.

WARNING There are several key application considerations and system specifications (bottom of drawing) when usingthese components (conversion module, cable and input module). Read and understand these considerationsbefore installation.

Cables are available in lengths of 0.5M or 1.0M (005=0.5M, 010=1.0M)

1492-CONACAB005T2 1756-IF6I

1756-IF6I

Conversion: 1771-IL (1) to 1756-IF6I (2) (Voltage)

Conversion Module Installation and Application Considerations Cables are available in lengths of 0.5M or 1.0M (005=0.5M, 010=1.0M).

SHIELD GROUNDING: In some installations, the field wiring shield was grounded on the 1771 chassis. If this was the case, the installer must remove these shield connections from the 1771 chassis and they can be connected to the grounding stud on the 1492-CM1771-LA004 module. The pre-wired cable used between the 1492-CM1771-LA004 module and the 1756-IF6I [1492-CONACAB005T2] provides a shield ground lug to ground the shield at the 1756 ControlLogix chassis, this must be connected. Do NOT connect this ground lug to the conversion module grounding stud.



This configuration uses two (2) 1756-IF6I output modules to replace a single 1771-IL 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. [Reference Doc: 41171-031]

Conversion Module Installation and Application Considerations This Bul. 1492 cable consists of 2 separate cables (cable “A” and cable “B”) wired to one 1756-OB16I 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-OQ module output resistive current limits versus 1756-OB16I limits are as follows: 1771-OQ 1756-OB16I w/ 1492-C005005XT a) Current/Point 2.25A 2A b) Current/Module 9A 8A c) Surge Current/Point 4A for 10ms 4A for 10ms

The 1771-OQ is rated 10V to 32V DC. The 1756-OB16I is rated 10V to 30V DC.

Refer to your 1771-OQ and 1756-OB16I Installation Manual wiring schematics and diagrams for more details. Ensure 1756 output module ratings are not exceeded. [Reference Doc: 41171-033]
