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.

Conversion Module Installation and Application Considerations
Cables are available in 2.0m, or 5.0m
Terminals starting with A are the lower row of terminals, B terminals are the upper row.
Follow your PLC Analog User Manual for proper shield grounding instructions.
RTN terminals are internally connected on the 1756-IF6I.
Terminals w1, w2, w3, are spares used for field wire convenience. NOTE: This is only true for module RTP3. The
Bul. 1492 cable does not connect to these terminals.
