Rockwell Automation 1492-CM1771-LA003 Analog & Digital I/O Conversion Module - Manual

Analog and Digital I/O Conversion Module
(Cat 1492-CM1771-LA003)
I. Description
This I/O Conversion Module provides for the conversion of (1) 1771, 4 Ch Analog I/O module to be converted to (1) 1756, 6 Ch
Analog I/O module and consists of the following:
(1) 1771 Module (4ch) to (1) 1756 Module (6ch)
(1) Conversion Module: 1492-CM1771-LA003
(1) Cable: 1492-CONACAB005E (Table 2)
(1) Conversion Mounting Assembly: 1492-MUA… (Table 1)
This I/O Conversion Module also provides for the conversion of (2) 1771 Digital I/O modules that also use the 1771-WC swing
arm. In this case, this I/O conversion modules provide for the conversion of (2) 1771, 8 pt. Digital I/O modules to be converted
to (1) 1756, 16 pt. Digital I/O module and consists of the following:
(2) 1771 Module (8pt) to (1) 1756 Module (16pt)
(2) Conversion Module: 1492-CM1771-LA003
(1) Cable: 1492-C005005XS (Table 2)
(1) Conversion Mounting Assembly: 1492-MUA… (Table 1)
These conversions are accomplished without the removal of any field wires from the existing 1771 Swing Arms. The existing
1771 Swing Arms fit directly onto the edge connector of the 1492 Conversion Modules. For the Analog I/O conversions, one
end of the 1492 Cable has (1) connector for the Conversion Module and on the other end is (1) Removable Terminal Block
(RTB) for the 1756 I/O module. For the Digital I/O conversions, one end of the 1492 Cable has (2) connectors, one for each of
the (2) Conversion Modules and on the other end is (1) Removable Terminal Block (RTB) for the 1756 I/O module. See the
photos below.
The I/O signals are routed through the 1492 Conversion Module(s) and the 1492 Cable to the appropriate terminals on the
1756 I/O module per the Wiring Diagrams in Section V. As standard, 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.
De-energize and lockout any and all power to all I/O field devices connected to the A-B 1771 I/O chassis,
and the power to the 1771 I/O chassis 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. WARNING
