Foot Notes:
To understand any issues concerning I/O module compatibility refer to the Installation Manuals for the specific I/O
modules involved.
Two conversions are possible using these two cables - (4 Voltage & 4 RTD) or (4 Current & 4 RTD) - see the Wiring
Diagrams for further details.
Two conversions are possible using these two cables - (4 Voltage & 4 Thermocouple) or (4 Current & 4 Thermocouple) -
see the Wiring Diagrams for further details.
These catalog numbers are for a 2.0M cable length. A 5.0M cable is also available. Change the 3 numerals in the
middle of the catalog number from "020" to "050" (Example: 1492-CONACAB020N1 becomes 1492CONACAB050N1).
Only 2 cables can be used at one time. Each cable attaches to 1 of the 2 connectors on the existing RTP module. Each
cable converts 4 of the 1771 channels to 4 of the 1756 channels. The other end of the cable attaches to 1 of the 2 new
1756 modules.
