Digital I/O Conversion Module
(Cat 1492-CM1771-LD014)
I. Description
This Digital I/O Conversion system provides for the conversion of (1) 1771, 8 point I/O module to (1) 1756, 8 point I/O
module OR (2) 1771, 8 point I/O modules to (1) 1756, 16 point I/O module and consists of the following:
(1) 1771 Module (8pt) to (1) 1756 Module (8pt)
(1) Conversion Modules: 1492-CM1771-LD014
(1) Cable: 1492-CONCAB005U, 1492-CONCAB005V, 1492-CONCAB005W (Table 2)
(1) Conversion Mounting Assembly: 1492-MUA… (Table 1)
(2) 1771 Module (8pt) to (1) 1756 Module (16pt)
(2) Conversion Modules: 1492-CM1771-LD014
(1) Cable: 1492-C005005X_ (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 Arms. The existing
1771 Swing Arms fit directly onto the edge connectors of the 1492 Conversion Modules. On one end of the 1492 Cables
are (1) or (2) connectors for the Conversion Modules. 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 IV. 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, Section III for further
details.
