I. Module Description

The 1492-CM800-LA002 conversion module provides field wire signal conversion from a Modicon® B877-111, analog, 16-channel, single-ended current or voltage input module to a ControLogix 1756-IF16, analog, 16-channel, single-ended current or voltage input module. The conversion module provides the mating connections to the B877111 swing-arm (terminal block) with the attached field wires. It routes those signals, via its 25-pin, D-shell connector and a 1492-ACABLEUB or 1492-ACABLEUA pre-wired cable to the compatible terminals of the 1756-IF16 (refer to the Wiring Diagrams on pages 2 and 3).

II. Module Installation

The 1492-CM800-LA002 conversion module must be installed in a 1492 conversion system base-plate and coverplate assembly. The installation of the module into the assembly is explained in the Installation Manual that ships with the conversion assembly. For a list of compatible assemblies refer to Appendix A.

III. Conversion Module Compatibility Matrix

 This is the cable length in meters and tenths of meters (e.g. 015 = 1.5 meters). Recommended cable length is 003 (00.3 meters).

De-energize and lockout any and all power to all I/O field devices connected to the Modicon 800 I/O housing, and the power to the 800 I/O housing 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.

IV. Conversion Module Wiring Diagram

The following diagrams show the connections from the existing B877-111 swing-arm, through the conversion module, 1492 cable and to the 1756-IF16 analog input module. The diagrams can be used as an aid in possible system troubleshooting.

Conversion: B877-111 to 1756-IF16 (Single Ended Current) with 1492-CM800-LA002

Conversion Module Installation and Application Considerations



The B875-111 indicated differential inputs. When it was configured for single ended inputs, it was referred to as a B877-111.



SHIELD GROUNDING: For single ended current analog inputs both the B877-111 and 1756-IF16 recommend grounding the field wiring shield at the analog source/device. As such, no shield ground modifications should be requried. The pre-wired cable used between the 1492-CM800LA002 and the 1756-IF16 [1492-ACABLE003UB] provides a shield ground lug to ground the shield at the 1756 ControlLogix chassis, this must be connected.



The B877-111 recommended placing jumpers from UNUSED to USED analog input channels. These jumpers MUST be removed or they will result in improper operation.



The B77-111 analog input ranges were configured by DIP switches on the module. The appropriate range for the 1756-IF16 is configured by software.



This design assumes that all inputs on the B877-111 were connected to current transmitters. If there was a mix of current and voltage transmitters, then modification of pre-wired cable will need to occur at the 1756-IF16 terminal block. Refer to the 1756-IF16 Installation Manual for modification details.



CASE GROUND: If connected, remove this wire from the B877-111 terminal block, as it serves no purpose for the 1756-IF16.



Refer to your B877-111 and 1756-IF16 Installation and User Manuals for additional information concerning comparisons of module wiring, features, and configuration details. [Reference Doc: 41170-764 (Version 03)]



There are several key application considerations and system specifications (bottom of drawing) when using these components (conversion module, cable and output module). Read and understand these considerations before installation.

 T1 The B875-111 indicated differential inputs. When it was configured for single ended inputs, it was referred to as a B877-111.  SHIELD GROUNDING: For single ended voltage analog inputs both the B877-111 and 1756-IF16 recommend grounding the field wiring shield at

the analog source/device. As such, no shield ground modifications should be requried. The pre-wired cable used between the 1492-CM800-LA002 and the 1756-IF16 [1492-ACABLE003UA] provides a shield ground lug to ground the shield at the 1756 ControlLogix chassis, this must be connected.

 The B877-111 recommended placing jumpers from UNUSED to USED analog input channels. These jumpers can be removed if desired. They

are not required on the 1756-IF16, but they will not impact its operation (in voltage mode) if they are left connected.

 The B77-111 analog input ranges were configured by DIP switches on the module. The appropriate range for the 1756-IF16 is configured by

software.

 This design assumes that all inputs on the B877-111 were connected to voltage transmitters. If there was a mix of current and voltage transmitters,

(Operating specifications are when installed in the Conversion System base / cover-plate assembly)

VI. Appendix A - 800 Housing to 1756 Chassis Conversion System Selection Process

1) Determine the number of 800 I/O modules actually used in the 800 I/O Housing to be converted to 1756.

2) Review the data in Column 5 from the below table, and select a 1756 I/O Chassis which meets your conversion needs from Step 1. Ensure the information from the I/O Conversion module table is reviewed first since in some cases, two 1756 modules are needed to replace one 800 I/O module.

3) Once the 1756 Chassis is selected, refer to Column 7 and select the Conversion Assembly.

 One chassis slot required for the ControlLogix processor or a remote I/O adapter type module.  The footprint and mounting dimensions of the 1492 Conversion Assembly (base plate and cover plate) match those of the

Modicon I/O Housing.

 Width dimension includes the 1756 Chassis power supply.  Surplus Chassis width as compared to the 800 I/O Housing is divided equally when mounting it on the Conversion Assembly.  Mounting holes for the 1756 I/O Chassis are pre-drilled and pre-tapped into the Conversion Assembly cover-plate.
