Digital I/O Conversion Module
(Cat 1492-CM1771-LD013)
I. Description
This Digital I/O Conversion Module provides for the conversion of (1) 1771, 32 point I/O modules to be converted
to (2) 1756, 16 point I/O module and consists of the following:
(1) 1771 Module (32pt) to (2) 1756 Modules (16pt)
(1) Conversion Module: 1492-CM1771-LD013
(1) Cable: 1492-CONCAB005S3 or 1492- CONCAB005S4 (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 are (2) Removable Terminal
Blocks (RTBs) for the (2) 1756 I/O modules, 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 (2) 1756 I/O modules 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.
