Rockwell Automation 1492-CM1771-LA004 Analog & Digital I/O Conversion Module - Manual

Analog and Digital I/O Conversion Module
(Cat 1492-CM1771-LA004)
I. Description
This I/O Conversion Module provides for the conversion of (1) 1771, 8 Ch Analog I/O module to be converted to
(1) or (2) 1756, 6 Ch Analog I/O module(s) and consists of the following:
(1) 1771 I/O Module (8ch) to (1) 1756 I/O Module (6ch)
(1) Conversion Module: 1492-CM1771-LA004
(1) Cable: 1492-CONACAB005F or 1492-CONACAB005K or 1492-CONACAB005L (Table 2)
(1) Conversion Mounting Assembly: 1492-MUA… (Table 1)
(1) 1771 I/O Module (8ch) to (2) 1756 I/O Modules (6ch) - (4ch) on each 1756 I/O Module
(1) Conversion Module(s): 1492-CM1771-LA004
(1) Cable: 1492-CONACAB005T1 or 1492-CONACAB005T2 (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-WF 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 Modules: 1492-CM1771-LA004
(1) Cable: 1492-C005005XT (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. On one end
of the 1492 Cable are (2) connectors for the 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(s) to the appropriate
terminals on the 1756 I/O module(s) 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
