Analog I/O Conversion Module
(Cat 1492-CM1771-LA002)
I. Description
This Analog I/O Conversion Module provides for the conversion of (1) 1771, 8 Channel I/O module to be converted
to (1) 1756, 8 Channel I/O module and consists of the following:
(1) 1771 Module (8ch) to (1) 1756 Module (8ch)
(2) Conversion Module: 1492-CM1771-LA002
(1) Cable: 1492-CONACAB005C or 1492-CONACAB005D (Table 2)
(1) Conversion Mounting Assembly: 1492-MUA… (Table 1)
This conversion is accomplished without the removal of any field wires from the existing 1771 Swing Arm. The
existing 1771 Swing Arm fits directly onto the edge connector of the 1492 Conversion Module. On one end of the
1492 Cable is (1) connector for the Conversion Module. On the other end is the Removable Terminal Block (RTB)
for the 1756 I/O module, as shown in the photo below. The I/O signals are routed through the 1492 Conversion
Module and the 1492 Cable to the appropriate terminals on the 1756 I/O module per the Wiring Diagrams in
Section V. As standard, both portions of 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.
