I. Module Description
The 1492-CM800-LD010 conversion module provides field wire signal conversion from a Modicon® B827-032, 20 to
28Vdc, 32-pt input module to a ControLogix 1756-IB32, 10 to 31.2Vdc, 32-pt input module. The conversion module
provides the mating connections to the B827-032 swing-arm (terminal block) with the attached field wires. It routes
those signals, via its 40-pin connector and a 1492-CABLEZ pre-wired cable to compatible terminals of the 1756IB32 (refer to the Wiring Diagrams on page 2).
II. Module Installation
The 1492-CM800-LD010 conversion module must be installed in a 1492 conversion base-plate and cover-plate 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 diagram shows the connections from the existing B827-032 swing-arm, through the conversion module, 1492
cable and to the 1756-IB32 input module. The diagram can be used as an aid in possible system troubleshooting.

Conversion Module Installation and Application Considerations
The input delay times for the B827-032 module versus 1756-IB32 module are as follows:
B827-032 1756-IB32
a) Off-to-On Delay
0.4ms 0.38ms (plus selectable filter)
b) On-to-Off Delay 1ms 0.42ms (plus selectable filter)
The B827-032 modules provided a fuse for input power. The 1756-IB32 is NOT fused.
Refer to your B827-032 and 1756-IB32 Installation Manual wiring schematics and diagrams for more details.
