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

Conversion Module Installation and Application Considerations

This Bul. 1492 cable consists of a cable wired to one 1756-IT6I2 RTB. Recommended cable 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-LA005 module.
The pre-wired cable used between the 1492-CM1771-LA005 module and the 1756-IT6I2 [1492-CONACAB005G] 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.

The 1771-IXE has 8 input channels. The 1756-IT6I2 only has 6 input channels. This module combination can only be used to convert the
signals if 6 or less channels were used on the 1771-IXE.

The 1771-IXE has built CJC (cold junction compensation) into the swing-arm. The conversion module [1492-CM1771-LA005] passes this CJC
signal to the 1756-IT6I2. Ensure that the 1756-IT6I2 is configured for external CJC.

The 1771-IXE input configuration was software configured, as is the 1756-IT6I2. Please ensure the correct configuration in the 1756-IT6I2.

Refer to your 1771-IXE and 1756-IT6I2 Installation and User Manuals for additional information concerning comparisons of module wiring,
features and configuration details. [Reference Doc: 41170-951 (Version 02)]
